TPS40170RGYR - 60V Sync Buck PWM Controller VQFN-20 | TI
The Texas Instruments TPS40170RGYR is a 4.5V to 60V wide-input synchronous PWM buck controller housed in a 20-pin VQFN (RGY) package measuring 3.5 mm x 4.5 mm. It drives external high-side and low-side N-channel MOSFETs to deliver point-of-load conversion with output current set by the inductor and FETs (no internal switch - controller topology). A buck controller is a switch-mode power supply (SMPS) controller that drives external MOSFETs to step down a higher DC input voltage to a lower regulated DC output voltage. The synchronous variant replaces the traditional Schottky catch diode with a low-side MOSFET, substantially improving efficiency at heavy loads and shrinking power dissipation. Buck controllers sit in the broader power management hierarchy of voltage regulators alongside LDOs, boost converters, and SEPIC/Cuk topologies. They are the topology of choice when VIN-VOUT headroom is large or efficiency must exceed what a linear regulator can deliver. Key features include a 4.5V to 60V operating input range, 0.6V to 57V adjustable output voltage range, programmable switching frequency up to 600 kHz, 1.2A peak gate-drive output current, internal 4.5V LDO bias supply, adaptive dead-time control, and internal bootstrap diode. The TPS40170RGYR also integrates overcurrent protection (HICCUP), undervoltage lockout (UVLO), thermal shutdown, and a PGOOD indicator for sequencing. The TPS40170 uses TI's voltage-mode control architecture with a precision internal reference and external compensation network, providing stable loop response across a wide range of operating conditions. The integrated high-side bootstrap diode simplifies PCB layout by eliminating an external discrete component, while adaptive dead-time control prevents shoot-through current between the high-side and low-side FETs during switching transitions. Typical applications include industrial 24V/48V bus point-of-load converters, telecommunications and networking equipment, automotive infotainment and cluster power, battery-powered systems with wide input ranges (e.g., 12V, 24V, 36V, 48V rails), test and measurement instruments, distributed power systems, and general-purpose step-down DC-DC conversion where high efficiency and compact form factor are required. When designing with the TPS40170RGYR, ensure the input capacitor (X7R, low ESR, placed close to the high-side FET drain) and bootstrap capacitor are properly sized. The RT resistor sets switching frequency, and the compensation network (RC around the COMP pin) must be tailored to the chosen inductor and output capacitor - default compensation values from the datasheet typical application circuit should be validated on the bench.

TPS40171RGYR - 60V Wide-Input Sync Buck Controller | Texas Instruments
The Texas Instruments TPS40171RGYR is a 4.5-V to 60-V wide-input synchronous PWM buck controller in a 20-pin VQFN (RGY) package with exposed thermal pad, designed for non-isolated point-of-load (POL) DC-DC conversion in industrial, telecom, and automotive systems. It supports output voltages as low as 0.6 V with internal reference, drives external N-channel high-side and synchronous low-side MOSFETs, and operates at a programmable switching frequency between 100 kHz and 600 kHz selected by RT/SS resistor. A buck controller is a type of switching-mode DC-DC controller that regulates a lower output voltage from a higher input voltage using an inductor as the energy-storage element. Within the power management hierarchy, it sits between a DC-DC converter and a switching regulator; the term "controller" specifically denotes that the device only provides gate-drive signals and does not include the power MOSFETs internally, allowing the designer to size external switches for the application current. Synchronous buck controllers replace the traditional diode with a low-side MOSFET to achieve higher efficiency, particularly at high load currents. Key features include 4.5-V to 60-V input range, 0.6-V to ~0.85*VIN adjustable output, programmable current-mode control with internal slope compensation, selectable between voltage-mode (VMC) and average-current-mode (ACM) control architectures, and a precision enable input with adjustable undervoltage lockout. The TPS40171 also integrates programmable soft-start, cycle-by-cycle current limiting, hiccup overload protection, and a power-good indicator for supply sequencing. Thermal performance is rated for a junction-to-ambient resistance of approximately 35 C/W on a standard JEDEC 4-layer board. Architecturally, the TPS40171 uses peak current-mode control with an internal transconductance error amplifier, providing excellent line rejection and simplified loop compensation. The MODE pin selects between voltage-mode (D-CAP-style) and current-mode operation; current-mode offers better transient response and paralleled-rail capability. Internal logic-level translation enables 100% duty-cycle operation for cold-crank survival in 12-V automotive systems. The TPS40171 is the higher-frequency (up to 600 kHz) sibling of the TPS40170 (up to 300 kHz), allowing the use of smaller external inductors and capacitors where efficiency trade-offs are acceptable. Typical applications include industrial 24-V and 48-V distributed-bus point-of-load regulators, telecom base-station intermediate bus converters, 12-V automotive infotainment and body-electronics rails, battery-powered test and measurement equipment, and any POL supply requiring high step-down ratios with high efficiency. The wide input range also supports USB-PD and e-mobility auxiliary rails. When designing with this device, choose the TPS40170 (300 kHz max) variant when lower switching loss in large power stages is critical, and choose TPS40171 when smaller magnetics and faster transient response are required. Always size the bootstrap capacitor for the high-side gate drive and place the input bypass capacitors as close as possible to the power-stage switching node to minimize parasitic ringing. According to the TI datasheet, the maximum operating junction temperature is +125 C and the part is rated for -40 C to +125 C ambient operation.

TPS51624 - 28V VR12.6 Step-Down Controller | Texas Instruments
The Texas Instruments TPS51624 is a driverless, fully SVID-compliant VR12.6 step-down controller for Intel CPU power systems, with a 4.5 V to 28 V input range, one- or two-phase operation, and a thermally enhanced 32-pin QFN package. It uses D-CAP+ architecture with overlapping-pulse support, undershoot reduction (USR), and overshoot reduction (OSR) to improve transient response and reduce required output capacitance. The controller works with selected TI Power Stage devices and DrMOS products. A step-down controller is a power-management semiconductor that regulates a higher input voltage to a lower processor or logic voltage. A driverless VR controller does not include the high-current gate-driver circuitry; instead, it controls external power-stage devices. This separates control functions from power delivery, allowing the selected external MOSFETs or DrMOS devices to determine current capability and thermal performance. The TPS51624 supports one- or two-phase configurations for processor rails and is designed around Intel Serial VID, or SVID, control. Its control features include USR and OSR, while the D-CAP+ architecture is intended to support fast transient response, high efficiency, and low output capacitance. The manufacturer product page identifies the device as a VR12.6-compliant, driverless step-down controller. The package is a space-saving, thermally enhanced 32-pin QFN, and the manufacturer specifies an operating temperature range of -40 °C to 105 °C. The verified distributor listing identifies the TPS51624RSMR orderable as a D-CAP+ controller in a 32-VQFN package. The exact electrical limits, pin functions, switching frequency, compensation settings, and thermal resistance must be confirmed against the manufacturer datasheet before layout release. Typical uses include Intel desktop and mobile CPU voltage-regulator modules, VR12.6-compliant processor rails, and multi-phase power systems using TI Power Stage or DrMOS devices. Because the controller is driverless, external power stages are required; the controller alone does not provide the high-side and low-side switching elements. The primary design consideration is validating the selected power-stage devices, inductor, MOSFETs or DrMOS components, output capacitance, and thermal layout as one complete VR design. SVID settings, current limits, slew behavior, and the chosen phase count must also be checked against the processor requirements and the TPS51624 datasheet.

A buck converter is a type of switching DC-DC regulator that efficiently reduces a higher voltage to a lower one. The TPS53315 belongs to the synchronous buck family, using both high-side and low-side MOSFETs for high efficiency, and sits within the broader power management IC hierarchy for point-of-load conversion. Key features include 12-A continuous output current, integrated 19-mOhm high-side and 7-mOhm low-side MOSFETs that minimize conduction losses, an accurate 1% 0.6-V reference, and an integrated boost switch that removes the external bootstrap diode. D-CAP control delivers fast load transient response without external compensation and is stable with ceramic output capacitors. Technically, the proprietary D-CAP architecture combines constant on-time control with adaptive on-time, enabling low output ripple and fast transient behavior. Overcurrent protection, thermal shutdown, and a power-good indicator improve system robustness. The exposed-pad VQFN package provides thermal performance around 25 C/W junction-to-ambient per internal data. Typical applications include point-of-load power for FPGAs, ASICs, and DSPs, as well as server, storage, networking, industrial, and telecom power rails where high efficiency and small size matter. Design tip: use at least 2 x 22 uF ceramic output capacitance for stability and pay careful attention to PCB layout of the power stage and exposed pad for thermal dissipation.
TPS53315 - 12A D-CAP Sync Buck Regulator | Texas Instruments
The Texas Instruments TPS53315 is a D-CAP mode, 12-A synchronous step-down (buck) switching regulator with integrated MOSFETs, housed in a 5 mm x 7 mm 40-pin VQFN package with exposed pad. It is designed for ease of use, low external component count, and compact power systems, with a 0.6 V to 5.5 V adjustable output and single-rail input support. A DC-DC switching regulator (specifically a synchronous buck converter) steps a higher input voltage down to a regulated lower output voltage using integrated power MOSFETs and an external inductor. The D-CAP control topology uses an internally compensated, constant-on-time architecture that eliminates complex external compensation networks and delivers excellent load transient response, placing the TPS53315 high in the power management IC hierarchy: buck converter -> switching regulator -> DC-DC converter -> PMIC. Key features include up to 12 A of continuous output current, one 19-mOhm high-side and one 7-mOhm low-side integrated MOSFET, an accurate 1% 0.6-V voltage reference, and an integrated boost switch for the high-side gate drive. The conversion input voltage range spans 3 V to 15 V, while the supply voltage (VDD) range is 4.5 V to 25 V, allowing a single rail to power both control and conversion stages in many systems. Architecturally, the D-CAP constant-on-time scheme provides near-constant switching frequency with fast transient response and low output ripple, requiring only a small set of external components: input/output capacitors, an inductor, and a feedback divider. This minimizes BOM cost and PCB area compared to traditional voltage-mode controllers with external FETs. Typical applications include point-of-load power for DSPs, FPGAs, and ASICs in networking, telecom, industrial, and computing equipment, where multi-amp core or I/O rails must be generated efficiently from a 5 V or 12 V intermediate bus. It also suits distributed power architectures and dense server memory rails. Design consideration: with 12 A output in a compact VQFN-40 package, PCB thermal design is critical - use generous copper pour on the exposed pad and follow the TI datasheet layout guidelines for the power stage loop to minimize EMI and voltage spikes.

A DC-DC switching regulator (also called a buck converter or step-down converter) is a power management IC that converts a higher DC input voltage to a lower DC output voltage with high efficiency by rapidly switching the current path between MOSFETs and smoothing with inductors and capacitors. TPS53318 sits within the larger hierarchy of point-of-load (POL) controllers and voltage regulators used between a system bus (e.g., 12 V or 5 V) and low-voltage digital or analog loads such as ASICs, FPGAs, and DDR memory. The D-CAP mode control eliminates the external compensation network required by voltage-mode and current-mode parts, dramatically reducing BOM count and design effort. Key features include an integrated boost switch (no external bootstrap diode needed in most cases), an Eco-mode for light-load efficiency, programmable soft-start, overcurrent and overtemperature protection, power-good output, and UVLO/OVP. The 22-pin PowerLFDFN package exposes a thermal pad that routes heat directly to inner PCB copper layers, supporting full 8-A continuous operation with proper board layout. Architecturally, TPS53318 uses TI's D-CAP adaptive on-time control with feedback from the output voltage through an internal resistor divider, sampled at the moment the high-side MOSFET turns on. This topology achieves fast transient response without a traditional Type-III compensation network, and the internal low-side synchronous MOSFET removes the need for an external Schottky diode. Typical applications include 12-V to 1.0-V to 3.3-V POL rails powering ASICs, FPGAs, and SoCs; DDR memory VTT termination; 5-V input distributed-bus converters in telecom and server cards; and industrial controllers fed from 24-V nominal rails. The wide 22-V abs-max input also tolerates transients from loosely regulated industrial supplies. When designing in, follow TI's recommended capacitor types (X5R/X7R ceramic with sufficient voltage derating) and ensure the exposed thermal pad has multiple thermal vias to inner copper planes for sustained 8-A operation.

A synchronous buck converter is a DC-DC switching regulator that uses two internally integrated MOSFETs and an external inductor to step a higher input voltage down to a lower, tightly regulated output voltage. Buck regulators form the core of modern point-of-load power management hierarchies, converting intermediate distribution rails (such as 12 V) into the low voltages required by processors, FPGAs, and memory, with far higher efficiency than linear regulators. Key features include the D-CAP control topology, which requires no external compensation network and delivers excellent load transient response, plus TI eco-mode technology that reduces switching frequency at light load to maintain high efficiency across the full load range. The internal 5-mOhm/2-mOhm MOSFET pair minimizes conduction losses at full 30-A output, while the accurate 1% 0.6-V internal reference supports low-voltage core rails. An integrated boost switch eliminates an external bootstrap diode. Technically, the device supports adjustable switching frequency (250 kHz to 1 MHz), adjustable current limit with thermal shutdown protection, and flexible soft-start control. The wide 1.5-V to 15-V conversion input allows direct operation from 12-V intermediate bus rails as well as 5-V and lower rails. Typical applications include server and network processor core power, point-of-load supplies for FPGAs, ASICs, and DDR memory, telecom and datacenter power stages, and distributed power systems where a compact 30-A stage with minimal external components is required. Design consideration: at 30-A output the power stage dissipation is dominated by conduction losses, so a solid PCB thermal layout with generous copper pour on the exposed thermal pad is essential for reliable continuous operation.

A synchronous buck converter is a DC-DC switching regulator that steps a higher input voltage down to a lower output voltage using two internal MOSFETs (high-side and low-side) alternating between input and ground. Compared with a linear regulator, a buck converter achieves high efficiency through switched-mode power conversion, and it sits within the broader hierarchy of power management ICs (PMICs), under voltage regulators and DC-DC converters. Synchronous rectification replaces the external freewheeling diode with a low-side MOSFET, reducing conduction losses. Key features of the TPS53511 include the D-CAP2 control topology, which provides fast transient response with no external compensation components, making the design cost-effective with a low external component count; integrated MOSFETs that eliminate the need for external power switches; and low standby current suited to always-on points-of-load. The adaptive on-time (AOT) architecture dynamically adjusts the switching pulse width against input and output conditions to maintain regulation across load ranges. Technically, D-CAP2 mode combines an internal ripple-generation network with an adaptive on-time scheme, enabling stable operation with small ceramic output capacitors and supporting a wide duty-cycle range for computing power systems.

Typical applications include points-of-load (POL) regulation in computing power systems, network and communication equipment, consumer electronics, and industrial subsystems requiring a compact, low-component-count 1.5 A buck stage. Cost sensitivity and fast load transients make it a strong fit for memory, SoC core and I/O rails. For design, choose an output capacitor with low ESR to support the D-CAP2 ripple-injection scheme, and verify minimum on-time limits when converting 18 V down to very low outputs. Keep the SW, BOOT and VIN loops tight on the PCB layout.

Technically, the D-CAP3 control topology is an adaptive on-time architecture that provides fast transient response to load steps without complex loop compensation, allowing a very low external-component count. Because switching frequency adapts to input and output conditions, the converter maintains good efficiency across light and heavy loads while supporting high step-down ratios from 18 V rails. Typical applications include powering FPGAs, ASICs, microprocessors, and DSP cores in networking, telecom, industrial, and server equipment, where a compact 8 A point-of-load solution from a 12 V intermediate bus is required. For design, note the device is specified from -40C to +85C ambient; at 8 A loads with 18 V input, thermal design of the exposed-pad PCB land pattern is critical, and all-ceramic output capacitance must be verified against D-CAP3 stability requirements.

Key features include the D-CAP+ control architecture, which enables fast transient response with low output capacitance, and OSR (oversampled ripple regulation) for tight regulation with low-ESR output capacitors. The PCNT pin allows selection between dual-phase and single-phase operation, optimizing light-load efficiency versus full-load capability. An integrated 8-bit DAC sets the output voltage digitally, and TI Eco-mode supports high efficiency at light loads. Technically, the dual-phase topology interleaves two switching phases, reducing input and output ripple current, allowing smaller passives, and spreading thermal dissipation across two MOSFET pairs. With integrated drivers, the part eliminates external driver ICs, shortening the gate loop and improving switching behavior. Output voltage, current limit, and switching behavior are programmed via pin straps and the voltage DAC, minimizing external component count. Typical applications include CPU and ASIC core power rails, DDR memory VDDQ supplies, network switch and router POL rails, and distributed 12V bus point-of-load conversion where a controller plus discrete FETs offers the best cost-per-amp. Design tip: keep the gate-drive loops short to the integrated drivers, size the inductor per datasheet recommendations, and use PCNT phase selection deliberately - single-phase saves quiescent power at light loads but doubles per-phase current stress at peak load.

The I2C telemetry loop supports fault status readback, enabling power-system monitoring in datacenter and base-station designs. Typical applications include 48-V server power shelves, GaN-based point-of-load converters, telecom rectifiers, and high-density networking equipment where a single-stage 48-V-to-1-V conversion eliminates an intermediate bus converter stage, improving efficiency and power density. When designing, follow the TI datasheet layout guidelines: keep the switch-node loop compact, place GaN power stages adjacent to the controller, and use the exposed thermal pad soldered to a solid ground plane for heat spreading and EMI control.
TPS53667 - 6-Phase D-CAP+ Buck Controller w/ PMBus | Texas Instruments
The Texas Instruments TPS53667 is a 6-phase, D-CAP+ step-down driverless buck controller with built-in NVM and a PMBus interface, designed for ASIC power and high-current point-of-load applications. It supports 0.5V to 2.5V output via 8-bit BOOT voltage selection with 5 mV steps, and is compatible with NexFET smart power stages such as the CSD9549x and CSD96497Q5MC. The controller is offered in a 40-pin WQFN package (6x6 mm, RTAT suffix) and is characterized for operation over industrial temperature ranges. A buck controller (also known as a step-down controller) belongs to the broader hierarchy of voltage regulator -> DC-DC converter -> power management IC -> semiconductor. Multi-phase buck controllers like the TPS53667 extend single-phase buck topologies by interleaving multiple switching phases to reduce input/output ripple, improve transient response, and distribute thermal dissipation - enabling >100 A core rails from a single controller IC. The TPS53667 is targeted at server, datacenter, and ASIC POL applications where multi-rail digital loads demand precise, programmable, and telemetry-enabled supply voltages. Key features include D-CAP+ modulation for ceramic output capacitor compatibility, PMBus v1.2 system interface for telemetry (VOUT, IOUT, temperature) and programmability (VID, fault thresholds), an internal non-volatile memory (NVM) for storing custom configuration, driverless architecture that drives external NexFET power stages, and on-chip protection including OVP, OCP, and thermal shutdown. The D-CAP+ hysteretic control scheme offers excellent transient response without a traditional compensation network, which simplifies loop design for high di/dt ASIC loads. The 6-phase interleaved operation, combined with PMBus-driven dynamic voltage scaling, makes this controller well-suited for advanced CPU/ASIC cores requiring fast load-step recovery. Typical applications include ASIC/CPU core rails in servers and datacenters, high-current point-of-load regulation for FPGA and SoC platforms, telecom and networking line-card processors, and AI accelerator card POL supplies. Multi-phase interleaving is essential where single-phase solutions would incur excessive ripple or losses. When designing with the TPS53667, pair it with TI's NexFET CSD9549x or CSD96497Q5MC power stages for a fully validated driverless solution. The PMBus address and BOOT voltage are set by external resistor straps, eliminating the need for a separate programming device on the production line.

The two channels (N + M) can be flexibly phase-assigned up to 12 total phases, supporting dual-rail designs such as VCORE plus VSOC. The device is fully compatible with TI NexFET power stages (such as the CSD and TPS power-stage families), enabling a complete controller-plus-power-stage solution with differential remote voltage sensing and per-phase current balance. Digital loop control provides programmable transient behavior and startup sequencing without external compensation components. Typical applications include Intel server CPU core rails (VR14), AI accelerator and GPU core power, high-current ASIC and FPGA point-of-load conversion, and storage or networking processor supplies. Design consideration: the controller requires configuration via NVM programming (TI Fusion Digital Power Designer) and careful layout of the differential remote sense lines and current-sense routing to the power stages; follow the TI datasheet layout guidelines for SW, VOSNS, and CS pins to achieve specified transient accuracy.
TPS536C9T - Dual-Channel 12-Phase D-CAP+ Controller | TI
The Texas Instruments TPS536C9T is a dual-channel (N + M <= 12 phase) D-CAP+ step-down multiphase buck controller with TLVR (trans-inductor voltage regulator) topology support, PMBus, and VR14 SVID interfaces, housed in a 48-pin VQFN (RSL) package measuring 6.00 mm x 6.00 mm with exposed pad. It operates from a 4.5 V to 17 V input range and regulates outputs down to 0.25 V, supporting up to 765 A total output current when paired with TI smart power stages. A multiphase buck controller is a power management IC that distributes a high-current step-down conversion across several interleaved phases, reducing input/output ripple, spreading thermal load, and improving transient response compared with a single-phase regulator. In the power management hierarchy, the TPS536C9T sits at the controller layer: it drives external smart power stages rather than integrating FETs, enabling server-class current levels far beyond what monolithic converters achieve. Key features include the D-CAP+ control architecture for fast transient response, low output capacitance, and strong dynamic current sharing; native TLVR support for modern CPU load-transient profiles; an integrated non-volatile memory (NVM) for pin-free configuration; and compliance with the Intel VR14 SVID specification alongside a full PMBus interface for telemetry, fault management, and runtime adjustment. Technically, the digital controller loops monitor per-phase current and temperature, and firmware-configurable parameters (stored in NVM) define phase count, switching behavior, and protection thresholds such as overcurrent, overvoltage, and overtemperature. The device is fully compatible with TI smart power stages (e.g., CSD95xxx family), simplifying design-in for multi-rail server and accelerator boards. Typical applications include VR14-compliant CPU core power for servers and workstations, ASIC/FPGA accelerator rails, high-current point-of-load conversion in networking and datacenter equipment, and 12-phase TLVR evaluation platforms such as the TPS536C7EVM-051. Design tip: because TLVR coupling and layout strongly affect transient performance, follow the TI layout guidelines for the SYNC/RESET and current-sense pins, and verify SVID boot sequencing against the platform's VR14 requirements.

TPS53915RVER - 12A Sync Buck D-CAP3 Regulator | TI
The Texas Instruments TPS53915RVER is a 12-A synchronous step-down (buck) switching regulator with an adaptive on-time D-CAP3 control mode, supplied in a 28-pin VQFN package with exposed thermal pad. It operates from a 1.5-V to 18-V input (4.5-V to 25-V bias) and produces an adjustable 0.6-V to 5.5-V output with 0.5% reference accuracy. A synchronous buck converter is a DC/DC switching regulator that uses two internal MOSFETs plus an inductor to step a higher input voltage down to a lower, well-regulated output. Within the power management hierarchy (regulator -> switching regulator -> SWIFT point-of-load converter), buck converters deliver high efficiency compared to linear regulators because power is transferred through inductive switching rather than dissipated as heat. Key features include integrated 13.8-mOhm high-side and 5.9-mOhm low-side MOSFETs supporting 12-A continuous output current, PMBus-based configuration of voltage margining, soft-start time, power-on delay, VDD UVLO level and fault reporting, and an integrated boost switch for the high-side gate drive. The D-CAP3 adaptive on-time topology provides fast transient response with very low external component count, simplifying layouts in space-conscious systems. Technically, the TPS53915 is trimmed at the factory to enable PMBus commands with a default switching frequency of 400 kHz. The device uses a current-consuming strategy for stability with low-ESR ceramic output capacitors and supports a wide duty cycle range, making it flexible across 5-V, 12-V and intermediate bus rails down to sub-1-V core voltages. Typical applications include point-of-load power for DSPs, FPGAs and ASICs, industrial and enterprise server power rails, and telecom/datacom 12-V distributed power systems requiring fast transient response and high current density. Design tip: ensure adequate PCB copper area on the exposed pad for heat dissipation at full 12-A load, and verify PMBus resistor straps or serial configuration choices against datasheet sequencing guidance before layout. Pricing shown is as of 2026-08-29.
TPS54060DGQ - 60V, 0.5A Step-Down Converter | Texas Instruments
The Texas Instruments TPS54060DGQ is a 60-V input, 0.5-A step-down DC/DC switching regulator with an integrated 200-mΩ high-side MOSFET, housed in a 10-pin PowerPAD MSOP (DGQ) package with exposed thermal pad. It delivers an adjustable output from 0.8 V to 58 V at up to 500 mA load, switching at up to 2.5 MHz from a wide 3.5 V to 60 V input rail. Per TI datasheet (SLVSAP4E), key headline parameters include 116 µA no-load quiescent current, 1.3 µA shutdown current, and 78% typical efficiency at 12 V input to 5 V output at full load. A buck (step-down) converter is a switched-mode power supply topology that converts a higher DC input voltage to a lower DC output voltage by rapidly switching an inductor/capacitor energy-storage network. Within the broader hierarchy, the TPS54060 belongs to the power management IC category, specifically the synchronous/non-synchronous buck converter sub-family. Current-mode control provides simple external compensation, a low-ripple pulse-skip Eco-Mode enables high efficiency at light loads, and the wide VIN range makes it ideal for industrial, automotive, and battery-powered applications with high transient rails. Key features include a precision enable pin with tighter threshold than its predecessor, internal soft-start, cycle-by-cycle current limit, thermal shutdown, and frequency foldback for short-circuit protection. The 10-pin MSOP PowerPAD package offers a low thermal resistance path that keeps junction temperature manageable even at sustained 500 mA loads. Internal compensation and minimum BOM (one inductor, input/output caps, feedback divider) simplify design-in. Architecturally, the device uses peak current-mode control with an internal 200-mΩ high-side N-channel MOSFET. The high-side drive and bootstrap capacitor are integrated, removing external complexity. Eco-Mode operation skips switching cycles at light loads to maintain high efficiency down to a few hundred microamperes of load, while pulse-width modulation (PWM) at 2.5 MHz keeps the output ripple low and enables small inductor selection. Typical applications include 24-V industrial sensor rails, 48-V telecom and PoE point-of-load conversion, battery-powered systems up to 60 V, HVAC fan/valve control, and small appliance motor supplies. The wide VIN range also suits automotive 12-V/24-V load-dump environments when post-transzorbs are present. When designing with this part, ensure the bootstrap capacitor (CBST) is a high-quality 0.1-µF X7R ceramic placed close to the BST and SW pins. Keep the SW node copper area compact to minimize EMI, and use a feed-through via pattern under the thermal pad for low-junction-temperature operation.

TPS54060DGQR - 60V 0.5A Step-Down Converter | Texas Instruments
The Texas Instruments TPS54060DGQR is a 60-V, 0.5-A step-down (buck) DC-DC converter with an integrated 200-mΩ high-side MOSFET, housed in a 10-pin thermally-enhanced HVSSOP PowerPAD (DGQ) package. It accepts a wide 3.5 V to 60 V input range, supports an adjustable output from 0.8 V to 58 V, and switches at 100 kHz to 2.5 MHz set by an external RT resistor, enabling small external LC filter components. A buck (step-down) converter is a switching DC-DC regulator that efficiently lowers a higher input voltage to a lower regulated output voltage by chopping the input with a power switch and averaging the resulting pulse train through an LC filter. Buck converters sit inside the broader switching regulator → DC-DC converter → power management IC hierarchy. They are preferred over linear regulators whenever the input-to-output voltage differential is large, because switching conversion avoids the linear regulator's I·(Vin-Vout) thermal loss. The TPS54060's low-quiescent Eco-Mode pulse skipping further improves light-load efficiency, making it well-suited to always-on applications. Key features include 116 µA operating quiescent current, 1.3 µA shutdown supply current via the enable pin, internal 0.8-V reference with ±1% accuracy, frequency synchronization to an external clock, power-good output, internal soft start, cycle-by-cycle current limit, and thermal shutdown. Current-mode control provides simple external compensation and flexible component selection, allowing engineers to optimize the loop for ceramic or electrolytic output capacitors. The integrated high-side MOSFET eliminates external switch selection and reduces BOM count. Typical applications include 24-V industrial automation rails, 48-V telecom and PoE point-of-load converters, HVAC and building automation sensor supplies, eMeter and grid infrastructure auxiliary rails, battery charging and management systems, and after-market automotive accessories operating from 12-V/24-V buses. The wide VIN range also suits distributed 12-V to 5-V/3.3-V/2.5-V intermediate buses in factory and process-control equipment. When designing with this part, place the bootstrap capacitor (BST to SW) close to the IC and keep the high-current SW loop area minimal to reduce ringing and EMI. Use the WEBENCH Power Designer tool to generate a complete reference schematic, compensation network, and inductor selection. The PowerPAD must be soldered to a sufficient copper area for thermal dissipation — up to ~1 W is achievable with a 1-in² copper pad on a standard 4-layer FR-4 board. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on the standalone manufacturer datasheet, helping engineers select, source, and qualify the TPS54060DGQR for production designs.
TPS54120 - Low-Noise 1A Buck + LDO Power Supply | TI
The Texas Instruments TPS54120 is a low-noise, 1-A integrated power supply that combines a high-efficiency step-down (buck) DC-DC converter with a high power-supply-rejection, low-dropout regulator (LDO) in a single 24-pin VQFN (RGY, 5.5 x 3.5 mm) package. The two-stage architecture delivers an ultra-low-noise regulated output for noise-sensitive analog loads while retaining the efficiency of switching conversion. An integrated power supply, or PMIC-style power stage, combines multiple regulation stages so a single IC replaces a discrete converter-plus-LDO chain. In the system power hierarchy, the TPS54120 sits within power management ICs (PMICs) -> voltage regulators -> DC-DC converters and LDO linear regulators. By cascading a buck converter with a low-noise LDO, the design attenuates switching ripple before it reaches the load, achieving far lower output noise than a buck regulator alone without the power penalty of an all-linear solution. Key features include a configurable switching frequency of 200 kHz to 1.2 MHz with frequency synchronization, adjustable soft-start for controlled inrush, power-good output for supply sequencing supervision, adjustable output voltages using external resistor dividers (down to 0.6 V reference per TI documentation conventions), and a fully configurable dc-dc and LDO stage. The high PSR of the integrated LDO stage suppresses buck ripple, making the output suitable for RF, clocking, and precision analog rails. According to the TI datasheet, typical applications include telecom infrastructure, pico and femto base stations, and powering sensitive clocking distribution where phase noise directly impacts system performance. The single-package integration reduces BOM count and board area versus a discrete two-chip solution. In design, place the buck switching loop components tightly, and give the LDO stage sufficient headroom so the LDO output stays in regulation; the LDO drop-out determines the minimum buck output setting for a clean final rail.
TPS54120 - Low-Noise 1A DC-DC + LDO Supply | TI
The Texas Instruments TPS54120 is a low-noise, 1A power supply that integrates a high-efficiency step-down DC-DC converter with a high power-supply-rejection low-dropout regulator (LDO) in a single 24-pin VQFN (5.5x3.5 mm) package. It operates from a 4.5V to 17V input, well suited to 12V power buses, with switching frequency adjustable from 200kHz to 1.2MHz. A power supply with an integrated DC-DC converter and LDO is a hybrid power management architecture within the voltage regulator family of power management ICs: the buck converter performs efficient step-down conversion, while the downstream LDO provides high power-supply rejection (PSR) and low output noise for sensitive loads. This two-stage approach in one IC eliminates the discrete two-chip design effort and is essential for powering clocking distribution, data converters, and RF circuits. Key features include adjustable output voltage up to 6.0V via external resistors, soft-start, switching-frequency synchronization to an external clock, spread-spectrum clocking (SSC) for EMI reduction, power-good output, output discharge, fixed UVLO, overcurrent protection, and synchronous rectification. The fully configurable converter and LDO allow a wide range of low-noise rail designs from a single device. Architecturally, the proprietary interaction between the buck stage and the LDO optimizes the efficiency-versus-noise trade-off: the converter handles the bulk voltage transformation, keeping LDO dropout small so PSR remains high with minimal efficiency penalty. The 24-VQFN (RGY) package provides a compact footprint with good thermal performance for space-constrained designs. Typical applications include telecom infrastructure, pico and femto base stations, and powering sensitive clocking distribution such as PLLs, VCOs, and high-speed ADCs and DACs, where clean rails directly improve phase noise and SNR. Design tip: keep the switching node short to minimize EMI, bypass the LDO output with a low-ESR ceramic capacitor for stability, and use the soft-start pin to control inrush current at power-up. Prices referenced are as of 2026-08-29.
TPS54202DDCR - 4.5V-28V 2A Sync Buck Converter | TI
The Texas Instruments TPS54202DDCR is a 4.5V to 28V input, 2A synchronous step-down (buck) converter in a compact 6-pin SOT-23-THN (DDC) package. It integrates two switching MOSFETs, internal loop compensation, and a 5ms internal soft-start, drastically reducing external component count and PCB footprint for point-of-load designs. A buck (step-down) converter is a DC-DC switching regulator that efficiently converts a higher input voltage to a lower output voltage using inductive energy storage and high-frequency switching. Unlike linear regulators, buck converters achieve high efficiency even with large input-to-output voltage differentials. As a synchronous buck, the TPS54202 replaces the freewheeling Schottky diode with an integrated low-side MOSFET, improving light-load and full-load efficiency within the power management IC family. Key features include the adjustable output range of 0.596V to 26V, a fixed 500kHz switching frequency, and Advanced Eco-mode operation that folds back switching frequency at light loads to extend standby efficiency. The 45uA quiescent current suits always-on and battery-backed systems. EMI-friendly design techniques ease EMC compliance, and integrated overcurrent and thermal shutdown protection ensure robustness. The -40C to +125C junction temperature range supports industrial environments. Architecturally, the device uses current-mode control with internal compensation, so no external compensation network is needed. Integrated low-RDS(on) MOSFETs deliver high efficiency in the small SOT-23-6 thin package, achieving high power density without a heatsink at moderate loads. Typical applications include 12V and 24V rail point-of-load conversion in set-top boxes, broadband and networking equipment, industrial supplies, and portable instruments. For example, it efficiently steps 12V down to 3.3V for digital logic with minimal ripple. Design tip: follow the datasheet recommendation of a 10uF input and 22uF output ceramic capacitor, and keep the SW/BOOT loops tight on the PCB; verify thermal relief on the exposed area for loads above 1.5A.
