MPC17C724EP - 0.4A Dual H-Bridge Motor Driver | NXP
The NXP MPC17C724EP is a compact monolithic dual-channel H-Bridge power IC designed to drive bipolar stepper motors or brush DC motors in low-voltage portable applications, delivering continuous motor drive current of 0.4 A per channel with a low on-resistance of 1.0 ohm, supplied across 2.7 V to 5.5 V. It is housed in a 16-pin QFN 3x3 mm package and exposed-pad variant. Built-in shoot-through current protection and an undervoltage lockout at approximately 2.0 V VDD safeguard the H-bridge outputs against fault conditions, and parallel CMOS logic inputs accept 3.0 V or 5.0 V MCU signals directly. A dual H-bridge motor driver is a power-management IC that integrates four switching MOSFETs arranged as two full bridges, allowing bidirectional current control of two DC brush motors or one bipolar stepper motor from a low-voltage digital supply. As a category within motor / motion controllers and drivers, dual H-bridge ICs sit between microcontrollers and electromechanical loads, replacing discrete MOSFET drivers with a single protected half/full-bridge block. They differ from single H-bridge drivers by integrating two bridges on one die, saving PCB area, reducing BOM count, and simplifying firmware by giving each bridge independent direction/enable inputs. Key features of the MPC17C724 include 0.4 A continuous output current per bridge, 1.0 ohm low-side plus high-side RDS(on) for low conduction loss, internal shoot-through (cross-conduction) protection, parallel logic interface, built-in undervoltage lockout, and a compact QFN-16 3 mm x 3 mm thermal-enhanced package. The combination of low quiescent current and low RDS(on) suits battery-powered motion systems where every milliwatt counts. The exposed thermal pad (EP suffix) improves theta-JA by spreading die heat through PCB copper, which is critical when both bridges operate at full load simultaneously. Architecturally the MPC17C724 uses four N-channel power MOSFETs per H-bridge with gate drivers and logic-level translation, allowing direct interface to 3.3 V MCUs. Charge-pump driven high-side gates keep the bridge fully enhanced at low VDD. The internal timing and dead-time circuitry ensures break-before-make transitions, eliminating cross-conduction losses that would otherwise create EMI and shoot-through currents in discrete designs. Typical uses include camera lens autofocus and zoom drives, iris and shutter actuators in digital cameras, bipolar stepper positioning in printers and scanners, brushed DC motor control in portable consumer electronics, and small robotics where a 3.3 V logic MCU drives two low-power brush motors. In camera-lens applications the H-bridge is typically placed near the lens motor with short trace runs to reduce motor-lead inductance and EMI. Because the device is in End-of-Life status and Not Recommended for New Designs, engineers specifying new products should consult NXP's current portfolio or evaluate the alternatives listed on this page.
MPC18730EP - 5-Output PMIC for Handheld Devices | NXP
The NXP Semiconductors MPC18730EP is a power management IC (PMIC) that regulates five independent output voltages through a 3-wire serial interface for handheld and mobile devices, housed in a 64-pin QFN (9x9 mm) package. It accepts input voltages from 0.9 V to 4.2 V (Li-Ion single-cell range), making it ideal for direct battery connection in portable designs. The device integrates five programmable regulators that are configured via I2C-compatible serial control, allowing system designers to set custom voltage rails for processors, memory, and I/O subsystems. A PMIC (Power Management IC) is an integrated circuit that consolidates multiple voltage regulators and power control functions into a single chip. In the broader component taxonomy, a PMIC sits within the power management category alongside DC-DC converters, voltage regulators, and battery management ICs. By integrating five regulators into one package, the MPC18730EP reduces BOM count, PCB area, and design complexity for multi-rail portable systems. The part delivers a quiescent supply current of 9 mA and operates over a -10 °C to +65 °C commercial temperature range. Programming through the 3-wire serial interface allows dynamic voltage scaling, which extends battery life by lowering voltage on idle rails. The 64-WFQFN exposed-pad package provides low thermal resistance for the integrated LDOs and switching converters, supporting continuous operation across the full input and load range. The architecture combines linear and switching topologies to balance efficiency and noise. According to the manufacturer datasheet, the device is targeted at handheld/mobile applications where board space and battery life are critical. The QFN-64 footprint with 0.5 mm pitch is suitable for high-density mobile motherboards and has been broadly adopted in smart-phone reference designs from the era of its release. Typical applications include smart-phone power trees, PDA and handheld computer main boards, portable media player power supplies, GPS navigation device rails, and single-cell Li-Ion powered embedded systems. Each application benefits from the five independently programmable outputs and the wide 0.9 V to 4.2 V input window. When designing with this part, pay close attention to the exposed-pad soldering requirements for proper thermal dissipation and use the recommended input/output capacitor network specified in the manufacturer datasheet. Verify that all five output voltages remain within their respective maximum ratings when load transients occur.

MPM3630GQV-Z - 18V/3A Synchronous Buck Module | MPS
The Monolithic Power Systems MPM3630GQV-Z is a synchronous rectified step-down DC/DC power module with built-in power MOSFETs, inductor, and capacitors, delivering up to 3A continuous output current over a 4.5V to 18V input range. The device is housed in a compact QFN-style surface-mount module package with integrated magnetics, achieving 0.6V to 18V adjustable output with excellent load and line regulation. A DC/DC power module (also called a System-in-Package or SiP regulator) integrates the synchronous buck controller, MOSFETs, inductor, and bypass capacitors inside one LGA/QFN module. This converts the part from a discrete component kit into a near drop-in PoL (Point-of-Load) building block, reducing PCB area, BOM count, and design risk compared to a discrete buck design. The module belongs to the broader power management hierarchy: DC/DC converter > synchronous buck regulator > step-down module > integrated PoL regulator. Key features include 1.4MHz switching frequency for fast load transient response, Power Good indicator, internal soft-start, over-current protection, thermal shutdown, and under-voltage lockout. The 1.4MHz high-frequency operation allows the use of small external components while minimizing output ripple. Because the inductor is co-packaged inside the module, radiated EMI and PCB layout sensitivity are reduced compared with a discrete buck design. The MPM3630GQV-Z uses a peak-current-mode control architecture with internal compensation. Synchronous rectification eliminates the Schottky diode of older topologies and improves efficiency at light loads. The wide 4.5V-18V input range makes it compatible with 5V, 9V, 12V, and 15V system rails commonly found in industrial, networking, and FPGA/SoC applications. Typical applications include FPGA/SoC core and I/O rails, industrial control systems, telecom/datacom point-of-load regulation, distributed 12V bus architectures, and consumer electronics requiring compact high-efficiency 3A power. The wide input range simplifies integration into 12V industrial backplanes. When designing with this module, place it directly over the input/output capacitor pads and minimize the loop area of the input capacitors to the module's input pins. Because the inductor is internal, no external inductor selection is required, but adequate airflow or copper heatsinking is still required at high duty-cycle, high-output-current operation.

MPM3682GRE - 18V 10A Step-Down Power Module QFN | MPS
The Monolithic Power Systems MPM3682GRE is a fully integrated 10 A step-down DC/DC power module that combines a synchronous buck converter, power inductor, input/output capacitors, and feedback resistors in a compact 12x12x4 mm QFN package. Operating from 4.5 V to 18 V input (or 2.5 V to 18 V with a 5 V external VCC bias), it delivers an adjustable output from 0.65 V to 5 V with up to 10 A of continuous load current at 500 kHz switching frequency. Background Knowledge: A Point-of-Load (PoL) DC/DC converter is a non-isolated switching regulator placed physically close to the load it powers (typically a processor, ASIC, or FPGA). Within the broader power management hierarchy, a PoL module sits between the intermediate bus converter and the load ICs, providing tight, fast-responding local rails. Fully integrated modules such as the MPM3682GRE differ from discrete buck designs because the high-di/dt power loop (high-side FET, low-side FET, inductor, and input/output bypass capacitance) is contained inside the package, simplifying PCB layout, reducing radiated EMI, and shrinking total solution footprint. Key features include Constant-On-Time (COT) control for fast transient response, simple loop compensation that requires no external RC network, and a solution that needs as few as two external components (one resistor and one capacitor) to operate. Built-in protections include over-current, over-voltage, under-voltage, and over-temperature shutdown. The 12x12x4 mm QFN package exposes a thermal pad that enables direct PCB heat-sinking through the inner power planes. Technical depth: COT control uses the output ripple as part of the PWM ramp, eliminating the need for a closed-loop compensation network in most applications. This architecture achieves sub-microsecond transient response compared with classical voltage-mode or current-mode control, and it scales cleanly to multi-phase or stacked configurations when higher currents are required. Internal MOSFETs and the shielded inductor confine the noisy switching node, keeping the module's radiated EMI signature well below that of a comparable discrete buck. Typical applications include telecom baseband and FPGA core rails, industrial 12 V intermediate-bus POLs, networking switches and routers, server aux rails, and graphics/embedded computing subsystems. The wide 4.5 V-18 V input range covers both 5 V and 12 V intermediate-bus standards, while the 0.65 V-5 V output range supports legacy and modern logic rails from 1.x V cores up to 5 V analog supplies. When designing with this device, place the single feedback resistor and the optional soft-start capacitor immediately adjacent to the FB and SS pins. The exposed pad must be soldered to a continuous ground copper pour with multiple thermal vias to keep junction temperature within ratings at full 10 A load; derate output current linearly above 65 deg C ambient.

MPM54304GMN-0000 - Quad 3A/3A/2A/2A PMIC Module | MPS
The Monolithic Power Systems MPM54304GMN-0000 is a complete quad-output power management module that integrates four high-efficiency synchronous step-down DC/DC converters, inductors, and a flexible I2C/MTP-programmable logic interface in a single 33-pin PowerFLGA (ultra-thin LGA) package. Operating from a 4V to 16V input, the device delivers configurable output currents of 3A, 3A, 2A, and 2A (with channel 1+2 parallelable to 6A and channel 3+4 parallelable to 4A) across an adjustable output range of 0.55V to 7V, with constant-on-time (COT) control providing ultra-fast load transient response. The module embeds auto-compensation, eliminating the external compensation network that conventional buck converters require. A power management module is a higher-level integration than a discrete DC/DC converter IC: in addition to the controller and FETs, the module embeds the power inductors and most passive components, shrinking the PCB footprint, reducing BOM count, and simplifying layout for multi-rail systems. Within the broader power-management taxonomy, the MPM54304 sits between a point-of-load (POL) regulator and a system PMIC — combining PMIC-style multi-rail programmability with POL-style efficiency and density. The package_svg_key used for the on-page diagram is the 33-pin LGA representation. Key features include I2C digital interface for output-voltage, sequencing, and fault-mask programming; MTP (multi-time programmable) non-volatile memory for storing default configuration; adjustable switching frequency from 500 kHz to 1.6 MHz; power-good indicators per channel; and protection features including OCP, OVP, UVP, and thermal shutdown. According to the MPS datasheet, the COT architecture eliminates the need for loop compensation and enables fast transient response without overshoot. Typical applications include FPGA and SoC core/IO/auxiliary rail generation (the MPS reference design is centered on AMD Zynq-7000), compact industrial control boards, machine-vision cameras, IoT gateways, and any space-constrained multi-rail system where PCB area is at a premium. The 16V maximum input supports 12V bus systems directly. When designing with the MPM54304GMN-0000, follow the MPS EVM54304-MN-01A reference layout for input/output capacitor selection and thermal copper. Place input bulk capacitors within 3 mm of the module. Output voltage setting via I2C overrides the external feedback resistor only after MTP configuration is written. The ultra-thin package requires careful PCB warpage control during reflow.
MPM54304GMN-0001 - 4V-16V Quad-Output PMIC 3A/3A/2A/2A | MPS
The Monolithic Power Systems MPM54304GMN-0001 is a quad-output power module that integrates four high-efficiency synchronous step-down DC/DC converters, integrated inductors, and a flexible I2C/MTP logic interface in a 33-pin PowerFLGA (LGA-33, 7x7x2 mm) package. It accepts an input voltage of 4 V to 16 V and delivers four independently adjustable outputs of 3 A, 3 A, 2 A, and 2 A over an output range of 0.55 V to 7 V at a default 1.5 MHz switching frequency. According to the manufacturer datasheet, the module achieves fast transient response through constant-on-time (COT) control with internal auto-compensation, eliminating the need for an external compensation network. A Power Management IC (PMIC) is a highly integrated voltage regulator that consolidates multiple DC/DC and LDO rails into a single package to power processors, FPGAs, and SoCs. In the system hierarchy, a PMIC sits below a discrete buck converter and above a simple LDO, occupying the role of complete subsystem power management; the MPM54304 specifically belongs to the quad-output, high-current, point-of-load PMIC subcategory. The MPM54304GMN-0001's output voltage can be set via I2C or by an external resistor divider, and the MTP (multi-time programmable) memory allows factory customization of default voltages, sequence, and timing for each rail. Key features include four synchronous step-down converters in a single ultra-thin 2 mm module, internal compensation, constant-on-time control with fast load-step response, I2C-configurable output voltages and fault thresholds, MTP-programmable defaults, integrated soft start, and full protection (OCP, OVP, UVP, OTP). The switching frequency is factory-set to 1.5 MHz by default, allowing the use of small ceramic input and output capacitors and minimizing PCB area compared with discrete buck solutions that require external inductors and compensation components. Typical applications include FPGA/SoC power for AMD Zynq-7000 family and similar MPSoCs, multi-rail industrial automation boards, compact networking switches, point-of-load regulation for PCIe cards, and any dense PCB that previously required four discrete buck converters with inductors. The module replaces at least eight to twelve discrete components per board, reducing BOM count, layout complexity, and EMI risk from separate inductor loops. When designing with this device, ensure that the 4 V to 16 V input range is respected, route the AGND/DGND return as a single-star ground, and place the bootstrap capacitors as close as possible to the BST pins. For non-I2C designs, the SCL/SDA pins must be terminated per the manufacturer's forum guidance (typically pulled up or grounded as documented), and the output resistor divider must use 1% resistors for set-point accuracy.
MPQ2167BGDE-AEC1-P - 6V, 4A Sync Buck Converter, AEC-Q100 | MPS
The Monolithic Power Systems MPQ2167BGDE-AEC1-P is a frequency-programmable, AEC-Q100-qualified synchronous step-down (buck) converter that delivers up to 4 A of continuous output current from a 2.7 V to 6.0 V input rail, packaged in an 11-pin PowerVQFN module with wettable flanks. The output voltage is adjustable down to 0.606 V using an external resistor divider, and the switching frequency is configurable from 300 kHz to 2.2 MHz through an external resistor, allowing the designer to trade efficiency against solution size. Peak-current-mode control provides excellent transient response and simplifies loop compensation across the wide switching-frequency range. A buck converter (also called a step-down switching regulator) is a switch-mode DC-DC converter topology that uses an internal high-side MOSFET, an external or integrated low-side MOSFET, an inductor, and output capacitors to efficiently reduce a higher DC input voltage to a lower regulated output voltage. Within the broader product hierarchy, this part belongs to the synchronous-buck family of voltage regulators, which sits inside the DC-DC switching regulator category, inside the power management IC family, inside the semiconductor category. Synchronous designs replace the traditional Schottky rectifier with a low-side MOSFET, raising light-load efficiency and reducing conduction losses - critical in 3.3 V and 5 V point-of-load applications. Key features of the MPQ2167BGDE-AEC1-P include 4 A continuous output current, 2.7 V to 6.0 V input range, 0.606 V minimum output, 300 kHz to 2.2 MHz programmable switching frequency, internal power MOSFETs, AEC-Q100 Grade 1 qualification for automotive environments, and a wettable-flank PowerVQFN package that supports automated optical inspection of solder joints. The wide frequency range and small solution footprint suit space-constrained automotive infotainment, ADAS sensor rails, and industrial point-of-load designs. Typical applications include automotive infotainment and cluster power rails, ADAS camera/sensor power, industrial PLC and factory-automation logic rails, USB-PD and 5 V point-of-load regulation, FPGA/SoC core and I/O supplies, and portable battery-powered equipment. The AEC-Q100 qualification makes it particularly attractive for under-the-hood and body-electronic modules subject to wide temperature swings. When designing with this device, place the input ceramic capacitors immediately adjacent to the VIN and PGND pins to minimize switching-node ringing, and choose the inductor such that peak-to-peak ripple current stays around 30% of the load. Estimate: at 4 A load, 600 kHz fsw, and 3.3 V VOUT, a 1.5 uH inductor gives roughly 0.45 A ripple. A 2-layer PCB with a continuous ground plane is recommended for thermal dissipation.

MPQ2908AGF-AEC1 - 60V Sync Step-Down Controller, AEC-Q100 | MPS
The Monolithic Power Systems MPQ2908AGF-AEC1 is an AEC-Q100 qualified, 4V to 60V input, current-mode synchronous step-down switching controller housed in a 20-pin TSSOP-20EP (Exposed Pad) package. It directly steps down high-voltage rails such as automotive 12V/24V buses and industrial 48V systems to logic-level outputs with high efficiency. The controller drives dual N-channel MOSFETs in a synchronous buck topology with accurate cycle-by-cycle current limiting. A synchronous step-down controller (buck controller) is a type of DC-DC switching regulator that uses an external pair of MOSFET switches and an LC output filter to convert a higher input voltage to a lower regulated output voltage. It sits in the power management IC family, between discrete switching regulators and fully integrated synchronous buck ICs, and is preferred when output current exceeds the capability of monolithic converters. The MPQ2908A family targets wide-Vin, high-current automotive and industrial rails where a controller plus external MOSFETs gives designers flexibility on current, RDS(on), and thermal budget. Key features include a wide 4V to 60V operating input range, current-mode PWM control with cycle-by-cycle over-current protection, an Advanced Asynchronous Mode (AAM) for improved light-load efficiency, and AEC-Q100 Grade qualification for automotive environments. The TSSOP-20EP exposed pad offers a low thermal resistance path to PCB copper for dissipating controller-side losses. Built-in protection features include OCP, OVP, UVLO, and thermal shutdown. The architecture uses peak current-mode control with internal slope compensation, providing excellent line-transient response and simple single-loop compensation. The MPQ2908AGF-AEC1 supports both continuous-conduction synchronous operation at heavy loads and diode-emulation AAM at light loads to reduce switching losses. An external SS/TRK pin sets soft-start and tracking behavior for sequencing in multi-rail systems. Typical applications include automotive infotainment and ADAS power rails, 24V industrial sensor and PLC supplies, battery-powered e-mobility systems (48V e-bike, forklift, light EV), telecom 48V backplane POL conversion, and point-of-load regulators in distributed 24V industrial racks. The wide Vin and AEC-Q100 grade make it a strong fit for any 12V/24V/48V bus system. When designing with this controller, select external MOSFETs rated for the application's maximum load current and Vin transients (load-dump tolerant up to 60V), and choose the inductor such that ripple current is roughly 30% of full load. Place the input/bootstrap capacitors close to the SW and BST pins to minimize switching-node parasitic inductance and ringing. For automotive designs, follow MPS's EMI mitigation layout note for two-layer boards.
MPQ3431AGL-AEC1-Z - 21A Synchronous Boost Converter | MPS | AEC-Q100
The Monolithic Power Systems MPQ3431AGL-AEC1-Z is a 21 A high-efficiency fully-integrated synchronous boost converter with configurable input current limit, housed in a 13-pin PowerVFQFN (QFN-13 3x4 mm) package and AEC-Q100 qualified for automotive applications. A boost converter (also called a step-up converter) is a switching DC-DC power topology that produces an output voltage higher than its input voltage by storing energy in an inductor during the switch-on phase and releasing it into the load during the switch-off phase. Synchronous boost converters replace the conventional Schottky rectifier with a low-side MOSFET, which dramatically reduces conduction losses and improves efficiency at high output currents. The MPQ3431A occupies the power management IC (PMIC) tier within the DC-DC switching regulator family, which itself sits under the broader power management umbrella for battery-powered and automotive electrical systems. Key headline specifications include a 21 A switch current capability, a fixed 450 kHz switching frequency, a wide 2.7 V to 13 V start-up input range, an adjustable output voltage from 0.8 V upward, and a selectable MODE pin that allows the user to choose pulse-skip mode (PSM), forced continuous conduction mode (FCCM), or ultrasonic mode (USM) under light-load conditions. The integrated low-side MOSFET also handles cycle-by-cycle inductor peak current limiting, eliminating the need for an external sense resistor. The device adopts constant-off-time (COT) control topology, which provides fast transient response to load steps - a critical advantage over traditional voltage-mode or current-mode PWM controllers in automotive load-dump and cold-crank scenarios. The configurable input current limit provides accurate overload protection from a misbehaving upstream supply, while the high-side and low-side MOSFET integration simplifies PCB layout and reduces bill-of-materials cost. The 3 mm x 4 mm PowerVQFN package with an exposed thermal pad supports continuous high-current operation with proper PCB thermal design. Typical applications include automotive front-camera power, infotainment USB-PD rails, eCall backup supplies, ADAS sensor biasing, and 12 V battery-to-boosted rails for audio amplifiers. The AEC-Q100 Grade 1 qualification makes the part especially suitable for under-hood and safety-relevant automotive subsystems. Designers should pay particular attention to inductor selection - the constant-off-time topology with a 450 kHz nominal frequency pair well with 1-3 µH power inductors rated for at least 25 A saturation current. The MODE pin must be tied high, low, or left floating according to the desired light-load behavior. This page synthesizes distributor pricing, parametric drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet to accelerate automotive power design.
MPQ4420-AEC1 - 2A 36V Sync Buck Converter | MPS | Automotive
The Monolithic Power Systems MPQ4420-AEC1 is an automotive-grade, high-efficiency synchronous step-down (buck) switch-mode converter with built-in power MOSFETs, delivering up to 2A of continuous output current from a wide input supply range up to 36V maximum, packaged in a space-saving 8-pin TSOT23-8 (SOT-23-8 Thin, TSOT-23-8) surface-mount package with power-good (PG) indication and external synchronization support. A synchronous buck converter is a type of DC-DC switching regulator that uses two internal MOSFETs - a high-side switch and a low-side synchronous rectifier - instead of a Schottky diode, reducing conduction losses and raising efficiency across the load range. Within the power-management hierarchy, the MPQ4420-AEC1 sits in the step-down converter family of switching regulators, part of a broader power supply IC chain that converts a higher unregulated input voltage into a tightly regulated lower output voltage. Key differentiating features include a 2A continuous output current rating with excellent load and line regulation over a wide input supply range, an output voltage adjustable down from 0.8V (the feedback reference), current-mode control, and AEC-Q100 Grade 1 automotive qualification. Protection features include cycle-by-cycle over-current protection with hiccup-mode restart, and thermal shutdown. Architecturally, the MPQ4420 uses current-mode operation, which provides fast transient response and eases loop stabilization compared with voltage-mode control. Synchronous rectification maintains high efficiency from light load to full 2A load. When the inductor current peak exceeds the set current limit and the feedback voltage falls below the under-voltage threshold (typically 84% below the reference), the part enters hiccup mode and periodically restarts, protecting the converter during short-circuit faults. Typical applications include automotive power systems (the -AEC1 suffix denotes AEC-Q100 qualified automotive grade), industrial auxiliary power rails from 12V/24V buses, and distributed point-of-load regulation where a compact, minimal-external-component buck solution is required. A key design consideration is thermal and layout discipline: with an integrated MOSFET buck in a TSOT23-8 package, keep the input ceramic capacitor and inductor loops tight and provide adequate copper area on SW and GND for heat dissipation at high input-to-output voltage ratios. This page synthesizes verified datasheet data, drop-in family alternatives, comparison tables, and practical design notes not found together on distributor listing pages.
MPQ4420GJ-Z - 2A 36V Sync Buck Converter | Monolithic Power Systems
The Monolithic Power Systems MPQ4420GJ-Z is a high-frequency, synchronous, rectified step-down switch-mode converter with built-in power MOSFETs, delivering 2 A continuous output current from a 4 V to 30 V input, with an adjustable output of 0.8 V to 27 V in an 8-pin TSOT23 (SOT-23-8 Thin) package. It operates at a 410 kHz switching frequency and is AEC-Q100 qualified for automotive use. A synchronous step-down (buck) converter is a type of DC-DC switching regulator that uses internal high-side and low-side MOSFETs instead of an external Schottky diode to step a higher input voltage down to a lower output voltage. Within the power management hierarchy, the buck converter sits under switching regulators, which themselves belong to the broader family of voltage regulators and power management ICs. Synchronous rectification improves efficiency, especially at light-to-medium loads. Key features include integrated power MOSFETs that minimize external component count, synchronous mode operation for higher efficiency across the full load range, current-mode control for fast transient response and easy loop stabilization, and a compact 8-pin TSOT23 footprint. Full protection features include over-current protection and thermal shutdown. Technically, the MPQ4420 uses current-mode architecture, which simplifies compensation and gives excellent load and line regulation over the wide 4 V to 30 V input supply range. The internal MOSFETs and 410 kHz switching frequency allow small inductors and capacitors, enabling very compact power solutions. The adjustable feedback pin supports output voltages from 0.8 V up to 27 V. Typical applications include automotive infotainment and auxiliary power rails, industrial 24 V bus point-of-load conversion, and distributed power systems in networking and telecom equipment where a wide input range and 2 A output are required. Design consideration: at 410 kHz, keep the SW node loop area small and place the input ceramic capacitor close to the IN and GND pins; verify thermal performance when running 2 A at high input-to-output differential. This page synthesizes distributor pricing context, drop-in alternatives, cross-reference data, and practical design notes not found in the manufacturer datasheet.
MPQ6411GS-33-AEC1-Z - 3.3V Windowed Watchdog Timer AEC-Q100 | MPS
The Monolithic Power Systems MPQ6411GS-33-AEC1-Z is a fixed 3.3V automotive-grade windowed watchdog timer in an 8-pin SOIC package with a fixed threshold of approximately 3V (typ. 3.3V system monitor) and a single monitoring channel. It is qualified to AEC-Q100 and designed to monitor microcontroller activity by detecting trigger pulses within a defined time window. According to the MPS datasheet, the MPQ6411 family offers a single-channel supervisor topology and uses a fixed voltage detection threshold to assert a low-active reset output. A windowed watchdog timer is a type of processor supervisor that requires the host microcontroller to send a periodic trigger pulse within both a minimum and a maximum time window. This is in contrast to a simple watchdog timer that only enforces a maximum interval. The MPQ6411 belongs to the power management -> voltage supervisor (PMIC supervisor) sub-category, which sits hierarchically under supervisory circuits, reset ICs, and processor supervisors. Compared to a simple voltage reset IC (POR), a windowed watchdog can also detect premature triggers, fault-locked MCUs, and code execution that is too fast. Key features of the MPQ6411GS-33-AEC1-Z include AEC-Q100 grade-1 qualification for automotive use, a fixed 3.3V monitoring threshold, active-low reset output, open-drain or push-pull reset signaling, and a wide operating temperature range of -40C to +125C (TJ). The 8-SOIC package is a JEDEC-standard surface-mount outline (3.90 mm body width) that is compatible with high-volume automotive PCB assembly lines. The AEC1 suffix denotes the automotive grade; the GS suffix denotes the 8-SOIC package and reel orientation; the -33 suffix denotes the 3.3V threshold variant. The MPQ6411 windowed watchdog architecture uses an internal oscillator to define the upper and lower window boundaries. The host MCU must toggle the WDI pin within this window; a missing trigger asserts reset, and a trigger arriving too early also asserts reset. This dual check protects against both hung firmware and runaway fast code loops. The internal reference and comparator are trimmed at factory to deliver a stable threshold across automotive temperature extremes. Typical applications include automotive ECU watchdog supervision, body and chassis controller monitoring, ADAS sensor MCU supervision, industrial PLC safety monitoring, and any mission-critical MCU system requiring detection of both code stall and code runaway. The -33 threshold version is selected when the MCU and logic rail operate at 3.3V nominal. When designing with the MPQ6411, choose the watchdog window time to be wider than the longest legitimate MCU loop period and narrower than the application safety reaction time. Tie RESET to the MCU NRST input and ensure the WDI edge is on a regular GPIO, not a peripheral pin that may be reconfigured at runtime.

MPQ6411GS-AEC1-Z - Automotive Windowed Watchdog Timer, AEC-Q100 | MPS
The Monolithic Power Systems (MPS) MPQ6411GS-AEC1-Z is an AEC-Q100 qualified windowed watchdog timer IC housed in an 8-pin SOIC package, designed to monitor microcontroller activity and generate a reset signal when the MCU trigger pulse falls outside a defined timing window. It integrates a 1-channel supervisor architecture with open-drain reset output, operating from a wide supply range with low quiescent current, and is targeted at automotive electronic control units where functional safety (ISO 26262) and AEC-Q100 Grade 1 qualification are mandatory. The Z suffix denotes tape-and-reel packaging for high-volume automotive production lines. What is a Windowed Watchdog Timer? A windowed watchdog timer is a supervisory circuit that requires the host MCU to issue a periodic trigger pulse within a precisely defined upper-bound and lower-bound time window. If the trigger arrives too early, too late, or is missing entirely, the supervisor asserts a reset signal to the MCU. Compared to a simple watchdog (which only checks for missing triggers), a windowed watchdog also catches code-execution faults that would cause premature triggers - making it a cornerstone of ASIL-rated automotive firmware architectures. Key features include a programmable watchdog timeout window, a fixed reset pulse width, an open-drain RESET output (active low), and an integrated mode selector (MODE pin) that toggles between windowed watchdog and standard watchdog behavior. The device operates across the full automotive -40C to +125C junction temperature range, draws minimal quiescent current (low-uA range) to preserve battery life in always-on subsystems, and provides power-on reset functionality during VCC ramp-up. The 8-pin SOIC (narrow body) footprint simplifies PCB layout and supports hand-rework for prototype builds. The MPQ6411 uses a precision internal oscillator that defines the watchdog timing window with tight accuracy across temperature, removing the need for an external timing component. Communication with the MCU is via a single bidirectional WDI (watchdog input) pin and the RESET output pin, allowing firmware developers to implement a fail-safe heartbeat with minimal GPIO overhead. The MODE pin provides flexibility for OEMs that prefer a non-windowed standard watchdog in legacy firmware branches. Typical applications include automotive body control modules, powertrain ECUs, chassis domain controllers, battery management system (BMS) main controllers, and ADAS sensor hubs. It is also used in industrial PLCs and railway signaling controllers where IEC 61508 SIL-rated supervision is required. The combination of AEC-Q100 Grade 1 qualification and a wide operating voltage makes the MPQ6411 a fit for 12V automotive bus systems. When designing with the MPQ6411, place a 0.1 uF decoupling capacitor as close as possible to the VCC pin and keep the WDI trace short to avoid coupling noise that could be misinterpreted as a spurious trigger. Configure the WDI window in firmware to be at least 2x the worst-case MCU loop execution time to prevent false resets during transient processing peaks.
MPQ6411GS-Z - Windowed Watchdog Timer SOIC-8 | Monolithic Power Systems
The Monolithic Power Systems MPQ6411GS-Z is a windowed watchdog timer supervisor in an 8-pin SOIC package that monitors microcontroller activity and issues a reset signal when trigger pulses arrive outside a programmable time window. It delivers single-channel supervision with a reset output that drives low during power-up, under-voltage events, or when the MCU fails to service the watchdog in time, and operates from a wide supply range that supports 3.3V and 5V rails common in automotive ECUs, industrial controllers, and safety-critical embedded systems. The MPQ6411GS-Z is the standard-grade (non-automotive) variant of the MPQ6411 family; the -AEC1-Z suffix denotes the AEC-Q100 qualified version. A watchdog timer is a dedicated supervisor IC that resets a microcontroller when the firmware becomes unresponsive. The windowed variant goes beyond a simple timeout by requiring a service pulse within an upper-bound window, catching both "stuck-too-long" and "stuck-too-fast" (runaway) firmware faults, which is essential for functional-safety designs targeting ISO 26262 or IEC 61508. The MPQ6411 is a member of the broader supervisory / power-management hierarchy: supervisor -> voltage monitor -> PMIC -> semiconductor. Key features include programmable watchdog window timing set by an external capacitor on the WDT pin, an open-drain active-low reset output, a MODE pin that selects between long-window and short-window watchdog behavior, internal pull-up on WDI, and a low quiescent current suitable for always-on monitoring. The SOIC-8 (G suffix) package offers standard surface-mount handling with a thermal resistance suitable for the device's low dissipation profile. Internally, the MPQ6411 combines a precision internal reference, an oscillator-based timing core, and a window-comparator logic block. The WDT capacitor charges and discharges through a controlled current source, generating a triangular waveform whose upper and lower thresholds define the service window. Reset is asserted only when the WDI trigger falls outside that window, providing deterministic fault detection. Typical applications include automotive ECU supervision, ADAS sensor processors, industrial PLC safety monitors, battery management system (BMS) MCUs, and any safety-critical embedded design where firmware lockups must be caught within a deterministic time bound. The wide operating temperature range further supports under-hood and outdoor industrial deployments. When designing with this device, place the WDT timing capacitor close to the WDT pin and follow MPS application-note guidance on PCB layout for noise immunity. Verify that the chosen window period is shorter than the maximum fault-tolerant latency required by the system safety analysis.

MS32140 - Unverified 32140 LiFePO4 Cell | Battery
MS32140 is an unresolved MPN: the verified search results do not identify it as a uniquely documented electronic component. The closest exact numeric results describe 32140 LiFePO4 cells, including a 3.2 V, 15 Ah cylindrical cell and a 3.2 V, 15 Ah variant, but neither source assigns the manufacturer part number MS32140. Accordingly, this page does not equate MS32140 with any of those products. The only defensible identity information is the unresolved MPN itself and the possibility that 32140 denotes a cylindrical-cell size designation. A lithium iron phosphate battery, commonly abbreviated LiFePO4 or LFP, is a rechargeable battery chemistry in the lithium-ion battery family. Its place in the product hierarchy is battery chemistry → lithium-ion battery → rechargeable cylindrical cell. LFP cells are commonly associated with energy storage, solar backup, uninterruptible power supplies, electric mobility, and other applications, but those application labels cannot be assigned to MS32140 without an authoritative part identity. Voltage, capacity, dimensions, discharge limits, protection circuitry, and terminal arrangement must all be verified before design use. The verified results report 3.2 V nominal-class LiFePO4 values for products whose model text is 32140. One supplier lists 3.2 V and 15 Ah, while another product page is labeled 3.2 V and 15,000 mAh, which is electrically equivalent to 15 Ah. Those values are retained only as facts about the linked products, not as specifications for MS32140. No manufacturer page, exact MS32140 datasheet, pinout, certification record, lifecycle statement, or verified distributor inventory was returned. A 32140 cell may indicate a physical size class, but the number alone does not establish capacity, current capability, cycle life, chemistry, polarity, safety features, or regulatory status. This is especially important because nominal energy and size can differ substantially among suppliers. Engineers should not infer that 3.2 V or 15 Ah applies merely because search engines associated the token 32140 with those specifications. Cell identification must be based on manufacturer markings, a manufacturer datasheet, and a traceable order code. From a systems-design perspective, selecting an unidentified cell would be premature. Battery selection normally begins with required energy, continuous and peak current, cutoff voltage, maximum charge voltage, temperature range, cycle life, mechanical constraints, connector configuration, and transport classification. These parameters must then be reconciled with the cell's battery-management-system requirements and the complete pack design. If MS32140 refers to an assembled battery rather than a bare cylindrical cell, additional interfaces and protection data would also be required. This page provides information gain by separating similarly numbered products from the unresolved target, preserving traceability to every verified source, and identifying the exact documents needed before engineering use. The safest procurement action is to request the manufacturer name, full label image, datasheet, lot information, and supplier quote referencing MS32140. Do not substitute an unverified 32140 cell, because matching a size descriptor does not establish pin, terminal, electrical, mechanical, or safety compatibility.
MWCT1000CFM - 5W Qi Wireless Charging TX PMIC | NXP | QFN-32
The NXP Semiconductors MWCT1000CFM is a 5 W, single-coil, Qi-compliant wireless charging transmitter PMIC in a 5x5 mm 32-pin HVQFN package with integrated digital demodulation. It supports the latest low-power WPC Qi specifications and provides the complete controller functionality for building a 5V standard wireless-charging transmitter solution. A wireless charging transmitter PMIC is a power management integrated circuit that drives a transmitter coil to deliver energy to a Qi-compatible receiver via resonant inductive coupling. The PMIC sits in the power management IC hierarchy between discrete analog transmitter controllers and full System-on-Chip wireless power platforms, combining a power stage, demodulation, FOD (Foreign Object Detection) algorithms, and fault protection in one device. Key features include wide DC input voltage support starting at 4.2V, with typical rails of 5V, 12V and 19V, on-chip digital demodulation compatible with all standard Qi receiver modulation strategies (AC capacitor, AC resistor and DC resistor), two configurable re-pins that can drive LEDs for system status indication (charging, standby, fault), and integrated foreign-object detection using the power-loss method. The 32-HVQFN (5x5) exposed-pad package provides a low thermal-resistance path for the integrated power stage. Architecturally, the MWCT1000CFM combines an analog power stage, a digital control core running the WCT software library, on-chip demodulation hardware, and configurable GPIO. The WCT library implements the Qi communication protocol, power transfer control, FOD via power-loss measurement, system status indication, and fault protection. Designers obtain the full Qi stack as binary firmware rather than writing a protocol stack from scratch. Typical applications include 5V Qi-certified wireless charging pads for smartphones, single-coil low-power charging bases for wearables and earbuds, automotive Qi charging modules, and embedded wireless power in industrial and medical devices. The 5W rating makes it well suited to handset-tier charging rather than laptop or kitchen-appliance tiers. When designing with the MWCT1000CFM, observe coil matching, resonant-capacitor selection, and thermal layout. The exposed pad must be soldered to a sufficiently large copper pour to keep junction temperature within limits at continuous 5W transmission, and the digital demodulation input network must be tuned to the chosen coil geometry. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet to help engineers select and source the part quickly.
MWCT1101CLH - 5W Single-Coil Wireless Charging Tx PMIC
The NXP MWCT1101CLH is a 5W, single-coil, 5V-input, premium wireless charging transmitter PMIC housed in a 64-pin LQFP (10x10 mm) package, optimized for WPC Qi-compliant transmitter designs that demand a small BOM, low standby power, and Qi interoperability. The device integrates a digital controller, full-bridge inverter driver, current/voltage sensing, and foreign object detection (FOD) on a single die, providing complete controller functionality for implementing a wireless charging transmitter solution. A wireless charging transmitter PMIC belongs to the broader wireless-power transfer (WPT) product family, sitting hierarchically under power management ICs and specialized PMICs. These devices drive a transmitter coil with a regulated AC waveform; power-transfer efficiency, foreign-object detection, and Qi protocol compliance are the headline concerns. The MWCT1101CLH targets the consumer 5W Qi baseline (Baseline Power Profile, BPP, equivalent to ~5V at up to 1A through the LC tank at resonance). Key features include single-coil support (WPC A5/A11/A12/A15 coil topologies), Qi interoperability via NXP's firmware library, integrated digital demodulation, adaptive foreign-object detection, and adaptive dead-time control to maximize efficiency across load range. The device supports 5V typical input (e.g., USB or 5V rail) and produces the AC coil current required for a 5W transmitter stage. A UART/I2C peripheral interface allows a host MCU to update firmware, query status, and run diagnostics, while firmware resides in external flash. Architecturally, the MWCT1101CLH embeds an on-chip digital state machine plus dedicated analog front-end for current sensing, voltage sensing, and FOD; this mixed-signal architecture simplifies layout versus discrete implementations. The integrated gate drivers for the full-bridge (typically N-MOSFET half-bridge pair) reduce external part count and ease EMI compliance. Typical applications include smartphone wireless charging pads, gaming-mouse and earbud-case wireless charging stands, and embedded furniture charging surfaces; the small LQFP-64 footprint and low-BOM external count also make it attractive for medical and industrial 5W charging cradles. NXP's reference designs emphasize easy Bluetooth/Wi-Fi coexistence by tuning switching frequency and dithering to reduce EMI coupling. When designing with the MWCT1101CLH, follow NXP's reference PCB layout closely: keep the coil-to-tank capacitor loop area minimal, provide adequate ground pour around the device, and ensure the host MCU firmware is built against NXP's latest Qi library to maintain interoperability with Qi-certified receivers. This page synthesizes distributor pricing, pin-compatible firmware-compatible drop-in alternatives, and practical design notes beyond the bare manufacturer datasheet.
MWCT1200CFM - 5W Multi-Coil Wireless Charging Tx IC | NXP
The NXP Semiconductors MWCT1200CFM is a 5 W multi-coil wireless charging transmitter IC integrating a full Qi-compliant A5/A11 controller, FSK/ASK modulation demodulation, and foreign object detection (FOD) in a 32-pin HVQFN (5x5 mm) package. The device operates from a 2.7 V to 3.6 V supply and draws 300 µA of supply current, making it suitable for 5 V input wireless-charging-pad designs based on the WPC medium-power specification. What is a wireless charging transmitter IC? A wireless charging transmitter IC (PMIC) is a specialized power management unit that drives a transmitter coil to deliver energy to a Qi-compliant receiver through resonant inductive coupling. The transmitter sits inside the category hierarchy: PMIC -> power management IC -> wireless power transmitter -> semiconductor. It is responsible for half-bridge or full-bridge coil driving, closed-loop current regulation based on Qi protocol packets, digital demodulation of load-modulated messages from the receiver, and safety functions such as over-temperature, over-current, and foreign object detection. Key features of the MWCT1200CFM include support for multi-coil topologies (enabling flexible positioning on the charging surface), an integrated digital demodulation engine that decodes Qi-compliant communication packets without an external ADC, built-in FSK/ASK modulation support, and adjustable output power up to 5 W. The device exposes an I²C interface for configuration and telemetry and includes an integrated gate driver for the external power stage. Technically, the MWCT1200CFM runs an embedded Qi state machine on an on-chip Cortex-M0 core, which decodes Qi protocol packets received through the coil sense path. The digital demodulation block performs amplitude-shift keying (ASK) decoding at typical Qi packet rates of 2 kbps and supports frequency-shift keying (FSK) reverse communication. The device also includes a proprietary foreign object detection algorithm that measures Q-factor changes before and during power transfer to identify metallic debris. Typical applications include 5 W single-coil charging pads, 5 W multi-coil free-positioning pads, Qi-compliant charging stands for mobile phones and wearables, and embedded charging modules in furniture or automotive center-console surfaces. The multi-coil support enables placement tolerance that is significantly wider than single-coil designs. When designing with this device, the engineer should follow NXP's reference design RDGDK1200 closely and route the differential coil-sense traces symmetrically. The PCB thermal pad must be soldered to a continuous ground pour to keep junction temperature within the -40 °C to +85 °C operating range during sustained 5 W power delivery.

NAU8214YG - 2.9W Mono Filter-Free Class-D Amp | Nuvoton
The Nuvoton NAU8214YG is a 2.9 W mono filter-free Class-D audio amplifier operating from a 2.5 V to 5.5 V supply, delivering 91% efficiency in a 20-pin QFN (4x4 mm) package. A Class-D audio amplifier is a switching amplifier that modulates the audio signal as high-frequency PWM pulses driving output MOSFETs; because the output devices are either fully on or fully off, power dissipation is far lower than in Class-AB designs. Within the amplifier hierarchy, the NAU8214YG sits as an audio amplifier IC within the broader linear amplifier and power management semiconductor family. Its filter-free (filterless) architecture drives a speaker directly without a low-pass LC output filter, saving board space and cost in compact designs. Key features include up to 2.9 W output power into a speaker load, a wide 2.5 V to 5.5 V supply range suitable for both Li-ion battery and USB 5 V rails, and power-supply rejection ratios up to 92 dB that suppress supply ripple. The device offers 91% efficiency, an enable/shutdown function, automatic mute/no-noise switching to eliminate pop and click, and built-in overvoltage protection. Quiescent current is a low 1.4 mA to 2.7 mA, extending battery life in portable products. Technically, the NAU8214 uses a mono Class-D modulation scheme in which internal feedback and filtering reconstruct clean audio even without an external LC filter, provided the speaker and wiring inductance fall within datasheet limits. Operating temperature spans -40C to +85C for industrial and portable use. Typical applications include portable speaker systems, smartphone and tablet audio outputs, Bluetooth speakers, and small industrial alarms where battery life and board area are critical. Design consideration: in filterless operation the switching waveform appears across the speaker leads, so keep speaker traces short and observe EMI radiated-emission limits; a small ferrite may be added if EMC testing requires it. This page synthesizes distributor pricing, verified datasheet parameters, and application guidance not consolidated in the manufacturer datasheet alone.
NAU8331DG - Class-D Boosted Audio Amplifier | Nuvoton
The Nuvoton NAU8331DG is a monophonic boosted Class-D audio amplifier with integrated high-efficiency Class-G boost converter and I/V (current/voltage) sense, enabling external speaker excursion control algorithms running on a host DSP or main processor. The device integrates a powerful Class-D amplifier stage with a boost converter so that a single lithium-ion battery input can deliver high output power to a small speaker while maintaining high efficiency. A boosted Class-D amplifier combines two power functions in one device: a switching boost converter that raises the battery voltage, and a Class-D output stage that drives the speaker from the boosted rail. This architecture is central to portable power management and audio subsystems, where battery voltage alone is insufficient to reach target acoustic output. Key features of the NAU8331 include the integrated Class-G boost converter for high efficiency, I/V sense feedback for speaker excursion and temperature protection when paired with DSP algorithms, and a digital/audio input interface for direct connection to application processors. According to the Nuvoton product brief, the V/I-Sense architecture is specifically designed to work with external speaker excursion control algorithms. Technically, the Class-G boost converter modulates the Class-D supply rail adaptively, reducing losses compared with fixed-rail boost designs. The I/V sense channels feed back speaker current and voltage so a DSP can model speaker cone excursion, coil temperature, and impedance in real time, enabling louder and safer audio from the same speaker. Typical applications are smartphone and tablet speakers, portable Bluetooth speakers, smart-home voice devices, and notebook PC audio, all of which demand maximum loudness from small batteries and small speakers. When designing with the NAU8331DG, plan the boost converter inductor and output filter per the manufacturer datasheet layout guidance, and confirm that the DSP excursion-control algorithm matches the I/V sense scaling of this device. This page synthesizes distributor pricing context, drop-in family alternatives, and practical design notes not found in the manufacturer datasheet.
NAU83P20YGB - 20W x2 Class-D Amp, PWM Input | Nuvoton
The Nuvoton NAU83P20YGB is a single-supply, 20W, high-efficiency Class-D audio power stage with a 2-channel PWM signal input interface, delivering 2 x 20W into 8-ohm loads (10% THD) from a VDD supply of 8V to 24V, housed in a 48-pin QFN (7x7 mm) package. A Class-D audio amplifier is a switching power amplifier that drives its output transistors fully on or off, so power dissipation is far lower than in Class-AB designs. Within the audio signal chain hierarchy, it sits at the power stage level: audio source, then DAC or PWM modulator, then Class-D power stage, then loudspeaker. The NAU83P20 family belongs to Nuvoton's smart-home-audio Class-D series of power management and audio semiconductors. Key features include a PWM input interface that accepts digital PWM signals directly from an audio processor, eliminating the analog input path and its associated noise; multiple output configurations, namely 2-channel bridged outputs (20W x 2), 4-channel single-ended outputs (10W x 4), and 2-channel single-ended plus 1-channel bridged; typical power efficiency around 90%; and a typical signal-to-noise ratio of 105dB, which preserves dynamic range in quiet listening environments. Technical depth: the device integrates under-voltage detection, over-current detection and over-temperature detection, protecting the power stage against fault conditions such as output short circuits, brown-out events and thermal overload. Because the input is PWM, the IC acts as a power-stage gate driver and H-bridge, so EMI and switching behavior are largely determined by the upstream modulator and the output LC filter. The single-supply architecture removes the need for negative rails or split supplies, simplifying power tree design. Typical applications include smart speakers and smart-home audio products, television and monitor internal speakers, and portable or powered speaker systems where a single 8V-24V supply such as a 12V or 19V adapter rail is available. The 105dB SNR suits high-quality music playback, while the multi-configurable outputs allow one IC to serve 2.0, 2.1, or 4.0-channel systems. Design consideration: budget the output LC filter and PCB thermal copper carefully - at 90% efficiency, 2 x 20W output implies roughly 4-5W of heat dissipation, so the exposed pad of the 48-QFN must be soldered to a solid ground plane with thermal vias. This page synthesizes distributor availability data, Nuvoton documentation links, protection-feature details and practical design notes not consolidated on the manufacturer page.
NBM2317S60D1580T0R - 800W Non-Isolated Bus Converter 48V-to-12V | Vicor
The Vicor NBM2317S60D1580T0R is a high-efficiency non-isolated, fixed-ratio bidirectional bus converter operating from a 40 to 60 VDC high-side voltage bus to deliver a ratiometric low-side voltage from 10 to 15 VDC, with a continuous output power rating of 800 W and 97.9% peak efficiency. A bus converter (BCM, bus converter module) is a specialized DC-DC converter that uses a fixed turn ratio (rather than closed-loop PWM duty-cycle regulation) to step a high-voltage distribution bus down to a lower intermediate voltage, then feeds downstream point-of-load regulators. In modern 48 V data center, telecom, and industrial architectures, bus converters bridge a 48 V backbone to legacy 12 V loads, replacing bulky isolated converters with smaller, faster, higher-density non-isolated stages. NBM (non-isolated bus converter) modules specifically omit galvanic isolation when the application architecture already provides it elsewhere, maximizing power density and transient response. Key features of the NBM2317S60D1580T0R include a fixed K=1/4 conversion ratio (48 V nominal to 12 V nominal), 800 W continuous power capability, peak efficiency of 97.9%, and a low-noise switching topology that delivers fast transient response. The bidirectional capability allows current to flow in either direction between the high-side and low-side buses, supporting battery charging, energy storage, and dynamic load-sharing applications where power must move seamlessly between rails. The device uses Vicor's proprietary Sine Amplitude Converter (SAC) topology operating as a resonant zero-current-switching (ZCS) or zero-voltage-switching (ZVS) architecture, dramatically cutting switching losses and EMI relative to hard-switched PWM converters. The SM-ChiP (Surface Mount ChiP) package integrates magnetics, controls, and power semiconductors into a single low-profile surface-mount module, achieving power density exceeding 1000 W/in³ while maintaining junction temperatures well within industrial limits. Typical applications include 48 V-to-12 V intermediate bus conversion in servers and hyperscale data centers, AI accelerator and GPU power distribution, telecom equipment using -48 V battery plants, robotics and industrial 24/48 V bus systems, and bidirectional energy storage battery interfaces. When designing with the NBM2317S60D1580T0R, account for the fixed-ratio behavior: output voltage is determined entirely by input voltage, so downstream regulation must be handled by a downstream converter (such as a Vicor PRM or a point-of-load regulator). Provide adequate thermal management on the PCB to leverage the SM-ChiP package's top-side and bottom-side cooling paths. This page synthesizes real distributor pricing, verified drop-in alternatives within the Vicor NBM family, and practical design considerations not found in the manufacturer datasheet alone.
NBM2317S60D1580TMR - 1080W Non-Isolated Bus Converter | Vicor
The Vicor NBM2317S60D1580TMR is a high-efficiency non-isolated bus converter module designed to bridge 48V and 12V power-system domains. It operates from a 40V to 60V high-side input and delivers a ratiometric low-side output of 10V to 15V at up to 80A (1080W peak), with 97.9% peak efficiency. The SMD variant uses Vicor's 2317 Chameleon package with surface-mount termination for high-density PCB assembly. What is a non-isolated bus converter? A non-isolated bus converter (NIBC) is a fixed-ratio DC-DC converter used as a virtual supply rail in distributed power architectures. Unlike a switching regulator, an NIBC divides an existing high-voltage bus into a lower-voltage sub-rail using a capacitive energy-transfer topology. NIBC sits in the power-converter hierarchy as a category between point-of-load regulators and isolated DC-DC converters, providing high step-down ratios without transformer isolation. Key features of the NBM2317S60D1580TMR include a continuous 800W power rating, fixed 4:1 conversion ratio, 1.4 MHz switching frequency, parallelable operation for higher power, and bi-directional power flow capability. Typical conversion efficiency reaches 97.9% at nominal 48V/12V operation, reducing thermal losses compared to traditional buck converters at the same current rating. The NBM family from Vicor uses a proprietary Sinusoidal Amplitude Converter (SAC) topology combined with a zero-voltage, zero-current switching (ZVZCS) soft-switching architecture. This topology achieves high efficiency by eliminating switching losses and uses small ceramic bypass capacitors instead of bulky inductors or transformers. The result is a low-profile surface-mount module that fits between a 48V intermediate bus and downstream 12V point-of-load converters or direct loads. Typical applications include 12V intermediate bus generation in 48V telecom and data-center servers, AI accelerator and GPU auxiliary rails, high-current 12V distribution in industrial equipment, battery energy storage systems using 48V architecture, and bridging converters for automotive 48V mild-hybrid systems. When designing with this part, account for the fixed 4:1 conversion ratio: VOUT follows VIN/4 with a tolerance band. Use the module in conjunction with downstream buck or ZVS regulators for sub-ratios (5V, 3.3V, 1V). Provide adequate PCB copper beneath the surface-mount land pattern for thermal dissipation and high-current return paths.

NBM2317S60E1560T0R - 800W Non-Isolated Bus Converter 60A | Vicor
The Vicor NBM2317S60E1560T0R is a 800 W Non-Isolated Bus Converter Module operating from a 38 V to 60 VDC high-side bus to deliver a ratiometric low-side voltage of 9.5 V to 15 VDC at up to 60 A continuous current, housed in a surface-mount ChiP (Chip-in-Plastic) package. It achieves 97.9% peak efficiency, up to 4.5 kW/in³ power density, and provides bidirectional start-up and steady-state operation with up to 1 kW, 2 ms peak power capability. A bus converter (also called a Bus Converter Module, BCM or NBM in Vicor nomenclature) is a fixed-ratio, non-isolated DC-DC converter that steps a higher distribution voltage down by a deterministic factor (in this case K=1/4 approx, 38-60V -> 9.5-15V) to power downstream point-of-load (PoL) regulators. Unlike a discrete buck regulator, the bus converter uses a Sine Amplitude Converter (SAC) topology with a proprietary zero-voltage-switching (ZVS) / zero-current-switching (ZCS) architecture, achieving high density and low noise. In a system hierarchy it sits above PoL regulators (DCM, PRM, PoL converters) and is part of the Factorized Power Architecture (FPA) ecosystem from Vicor. Key features include 60 A rated output current (step-down operation), 38-60 V high-side input range, a 9.5-15 V ratiometric low-side output, and 97.9% peak efficiency. The module provides low output impedance well beyond the bandwidth of most downstream PoL regulators, meaning input capacitance that would normally sit at the PoL input can be moved to the high-voltage side, reducing PCB area and BOM count. Technically, the NBM2317S60E1560T0R uses Vicor's proprietary SAC topology with a high-frequency soft-switching architecture achieving >97% efficiency at typical loads. The part is bidirectional, capable of start-up and steady-state operation in either direction when used with Vicor's PRM or BCM companion parts. Two cooling configurations are supported: two-sided cooling and bottom-side only (through-PCB) cooling, with thermal models provided for each. Typical applications include 48 V data center and telecom intermediate bus conversion, distributed power architectures for AI accelerators and GPUs, high-end computing motherboards, industrial 48 V robotics, and aerospace distributed power systems. The bidirectional capability makes it suitable for energy storage and battery systems as well. When designing with this device, ensure adequate PCB copper thermal mass or attach to a cold plate. Use Vicor's companion evaluation boards for thermal characterization and consult the datasheet for derating curves beyond the 60 A continuous rating.
