FDMF6704V - 1MHz DrMOS Module with LDO | onsemi
The onsemi FDMF6704V is a high-frequency DrMOS power-stage module for synchronous buck converters, integrating a driver IC, two power MOSFETs, a bootstrap Schottky diode, and a 5 V gate-drive LDO regulator in a 40-MLP package measuring 6 mm x 6 mm. The module supports operation from a single 12 V power supply and is optimized for switching speeds up to 1 MHz. Its integrated gate-drive LDO supplies a regulated 5 V gate-drive rail. A DrMOS module is an integrated power-stage device that combines a half-bridge MOSFET pair with its associated driver circuitry. In the power-conversion hierarchy, it sits between discrete power MOSFETs and a complete DC-DC converter controller: the FDMF6704V accepts a PWM command and supplies high-side and low-side gate drive, while the surrounding converter determines output voltage, current, and feedback conditions. The main benefit of integration is compact PCB area and a short gate-drive path. According to the onsemi datasheet, the 6 mm x 6 mm MLP occupies 44% less space than conventional 8 mm x 8 mm DrMOS packages. Integration also reduces the number of separately placed power-semiconductor and driver components, simplifying assembly in high-frequency synchronous buck designs. The internal high-side and low-side MOSFETs form the efficient switching section of a synchronous buck converter. Its integrated bootstrap Schottky diode supports the high-side gate-drive circuit, while the internal LDO produces the 5 V supply required by the driver. At switching speeds up to 1 MHz, careful layout, low-inductance power loops, adequate copper, and thermal management remain essential. Typical uses include compact CPU and GPU voltage-regulator modules, notebook and tablet power systems, telecom and networking equipment, and other high-current point-of-load converters. The module is most suitable when board area is constrained and the converter can be designed around its integrated 12 V input and 5 V gate-drive architecture. Designers should keep the VIN power loop, phase node, and bootstrap connections compact while providing low-impedance gate-drive return paths. Thermal performance depends on the exposed package structure, PCB copper, loading, switching frequency, and ambient temperature; verify worst-case junction temperature against the manufacturer limits. This page consolidates the verified onsemi and distributor information, distinguishes verified FDMF6704V facts from unavailable data, and records the absence of confirmed drop-in replacements rather than presenting unverified equivalents as drop-in parts.

A PoE PD interface is the front-end circuit that performs detection, classification, and inrush-current limiting when a device such as an IP camera, wireless access point, or network switch is powered over Ethernet cabling. It sits within the power management IC hierarchy, bridging the IEEE 802.3at physical layer and the downstream isolated or non-isolated DC-DC converter that generates the system rails. Key features include full compliance with the IEEE 802.3at high-power PoE standard, integrated detection and classification signature circuits, and a built-in current-mode DC-DC controller with a maximum switching frequency of 278 kHz, enabling compact magnetics and high conversion efficiency. The device supports up to 1.1 A output current capability in switching controller operation, and the PowerPAD HTSSOP-20 package provides low thermal impedance for high-power PD designs. Technically, the PD interface handles the 25 kOhm detection signature, class signaling, and controlled inrush startup, while the PWM section uses peak current-mode control for cycle-by-cycle current limiting, good transient response, and straightforward loop compensation. This single-chip integration reduces external component count compared to a discrete PD controller plus separate PWM controller solution, improving reliability and BOM cost in high-volume network hardware. Typical applications include IEEE 802.3at powered IP network cameras, 802.11ac/ax wireless access points, VoIP phones, PoE-enabled LED lighting drivers, and industrial Ethernet endpoints that must draw 25.5 W or more from the PSE. Design consideration: verify the external MOSFET and sense resistor ratings against the inrush and fault current limits, and follow the PowerPAD layout guidance for thermal dissipation.

HPA01124PWPR - IEEE 802.3at PoE Interface + DC/DC Controller | TI
The Texas Instruments HPA01124PWPR is an IEEE 802.3at high-efficiency Power over Ethernet (PoE) interface and DC-DC controller that integrates powered-device (PD) interface functions with a current-mode switching controller, delivering up to 1.1 A output current while operating from a maximum input voltage of 57 V. It is housed in a 20-pin HTSSOP (PW) package with power pad and is rated for operation from -40C to +125C, making it suitable for automotive-grade and industrial designs. A PoE interface and DC-DC controller is a power management IC that performs the IEEE 802.3at powered-device handshake (detection, classification, and inrush-current limiting on the Ethernet power pair) and then controls an external DC-DC converter stage that steps the 48V-class PoE input down to the system rail. In the power management hierarchy it sits between the PoE front end and the point-of-load regulators in powered devices such as IP cameras, wireless access points, and VoIP telephones. Key features of the HPA01124PWPR include compliance with the IEEE 802.3at standard (Type 2, up to 25.5 W at the powered device), a current-mode control architecture that simplifies loop compensation and gives fast transient response, high conversion efficiency for reduced thermal stress, and an extended -40C to +125C operating range. The single-chip integration of the PoE interface and switching controller reduces bill-of-material count compared with two-chip discrete solutions. Architecturally, the device combines the PD interface block with a PWM switching controller that drives external power MOSFETs. Current-mode control provides cycle-by-cycle current limiting, which protects the external MOSFET and transformer during overload and startup inrush events. The 57V maximum input rating covers the worst-case PoE PSE output voltage plus cable drop. Typical applications include IEEE 802.3at powered devices such as network IP security cameras, 802.11ac wireless access points, and PoE-powered LED lighting and building-automation nodes, where a single Ethernet cable must deliver both data and up to Class-4 power. When designing with this device, verify the external MOSFET voltage rating against the 57V maximum input plus switching spikes, and follow the datasheet layout guidance for the power-pad thermal connection.

HT79171 - 500kHz Sync Boost Converter 2A | Holtek
The Holtek HT79171 is a 500kHz synchronous step-up PWM DC-DC converter with a 2.2V to 5.0V input range, 2A continuous output current capability, and 5A peak current limit, housed in an 8-pin ESOP-8 package with exposed pad. It integrates ultra-low RDSON power MOSFETs rated at 25mOhm (main FET) and 45mOhm (synchronous FET), eliminating the need for external rectifier or control transistors. A synchronous step-up (boost) converter is a class of switching voltage regulator that raises a lower input voltage to a higher regulated output voltage. Unlike non-synchronous boost topologies that use a Schottky diode as the rectifying element, a synchronous boost replaces the diode with an integrated MOSFET, reducing conduction losses and significantly improving conversion efficiency, which is critical in battery-powered systems. Boost converters sit within the broader power management IC hierarchy, alongside buck (step-down), buck-boost, and charge-pump regulators. Key differentiating features of the HT79171 include its 500kHz fixed switching frequency, which permits the use of small inductors and ceramic capacitors for a compact bill of materials, its wide 2.2V to 5.0V input span that covers single-cell lithium-ion battery discharge curves (typically 2.5V to 4.2V), and its adjustable current limit. According to the Holtek datasheet, connecting a resistor of 20kOhm to 100kOhm on the OC pin scales the default 5A peak current limit down to as low as 1A, allowing designers to trade peak capability against inductor saturation margin. Architecturally, the HT79171 uses a PWM control scheme with integrated power switches optimized for low RDSON to maximize efficiency at multi-amp load currents. The synchronous rectification stage avoids the large diode-drop losses that would otherwise dominate at low output voltages, improving light-load behavior and overall conversion efficiency. Internal protection features include cycle-by-cycle peak current limiting and fault handling suitable for battery-powered designs. Typical applications include portable power banks (the primary documented use case), lithium-battery-powered portable equipment, and any 2.2V to 5.0V input boost regulation rail up to 2A continuous output. The 500kHz switching frequency supports small-footprint USB power bank PCBs. A key design consideration is inductor selection: the inductor saturation current must exceed the configured peak current limit with margin, since the OC pin setting directly determines peak inductor current.

HUB2200-S - 2200 µF Hold-up Box for VIPAC | Vicor
The Vicor HUB2200-S is a 2200 µF hold-up capacitor module designed as a dedicated accessory for the Vicor VIPAC family of component power front-end systems. Packaged as a sealed hold-up box/arm sized at 2.858 inches, it provides the bulk energy storage required to ride through input-voltage dropouts and brownouts that would otherwise reset or interrupt downstream DC-DC converter rails. Within the broader VIPAC ecosystem, the HUB2200-S plays the role of an external hold-up (energy storage) module. A VIPAC front-end is a complete AC-DC or DC front-end subsystem; the HUB2200-S bolts onto it and adds capacitance so that, when the input bus sags, the downstream converter modules see a sustained input voltage long enough to maintain regulation. This category of hold-up capacitor belongs to the larger family of bulk energy storage accessories used with modular AC-DC front-ends and DC-DC hold-up circuits. Common synonyms for these modules are "hold-up box," "hold-up capacitor," "bulk storage module," and "DC hold-up accessory." Key features of the HUB2200-S include a 2200 µF bulk capacitance rating, a hold-up box/arm form factor of 2.858 in, and electrical/mechanical compatibility with all VIPAC-family front-end power supplies. Each module is engineered, tested, and supplied by Vicor, the original manufacturer of the VIPAC platform, ensuring that hold-up time, inrush behavior, and discharge characteristics match the front-end's published specifications. The module connects to the VIPAC via the dedicated hold-up interface on the front-end chassis and is intended to be field-replaceable without desoldering. Technically, the HUB2200-S is built around low-ESR aluminum electrolytic capacitor technology optimized for high-energy pulse discharge rather than ripple filtering. The 2.858 in package is keyed to the VIPAC hold-up rails, providing both positive and negative polarity protection. It is specified for use across the industrial temperature range typical of VIPAC deployment and is integrated into the front-end's safety/ground scheme. Designers typically select the capacitance value to achieve a target hold-up time at a given minimum input voltage, using Vicor's published hold-up time vs. capacitance curves. Typical applications include industrial process-control PLCs, factory-automation controllers, railway signaling electronics, military COTS power subsystems, and any VIPAC-powered system that must comply with ride-through specifications such as SEMI F47 or IEC 61000-4-11. The HUB2200-S is also used in medical and test & measurement instrumentation where brief input-voltage sags cannot be allowed to corrupt measurements or reboot processors. When designing with the HUB2200-S, verify the VIPAC front-end variant it is mating to - different VIPAC SKUs accept different hold-up box sizes, and pairing the wrong value can either under-size hold-up time or cause the front-end's inrush limiter to interpret the capacitance as a fault. Always consult the VIPAC datasheet and the HUB2200-S installation guide before substitution. This page synthesizes distributor pricing, alternatives sourcing notes, and practical VIPAC integration guidance not found in a single manufacturer datasheet.

It is a buck regulator / step-down DC-DC controller IC supporting positive, isolation-capable output topologies for switch-mode power supplies. A resonant mode controller is a type of DC-DC switching controller that drives the primary switches of an LLC resonant converter. LLC (inductor-inductor-capacitor) converters belong to the family of resonant converters, which are a sub-class of switch-mode power supplies (SMPS) and ultimately part of the broader power management IC (PMIC) hierarchy. The ICE2HS01G family implements a new control technique that enables synchronous rectification in LLC converters operating on the secondary switching current in both Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) conditions, eliminating the need for a dedicated secondary-side synchronous rectification controller IC. Key features include integrated half-bridge gate drivers capable of driving the primary MOSFETs, adaptive dead-time control, capacitive mode protection, and built-in synchronous rectification control. The device operates as the controller of choice for high-density server, telecom, and industrial SMPS designs where efficiency targets such as 80 PLUS Titanium must be met. Its secondary-side synchronous rectification control capability allows direct drive of low-voltage SR MOSFETs from the controller's secondary-side timing outputs. Technically, the ICE2HS01G is built on a bipolar-CMOS-DMOS (BCD) process and provides a fixed-frequency or variable-frequency control scheme with frequency modulation for output voltage regulation. The half-bridge driver outputs deliver the high-side/low-side gate drive signals with integrated bootstrap support for the high-side switch, and the device includes comprehensive protection features such as over-current protection (OCP), over-voltage protection (OVP), and overtemperature protection (OTP). Typical applications include 600 W to 2 kW LLC resonant converter power supplies for server and data-center 12 V / 48 V rails, telecom rectifier front-ends, industrial SMPS, and high-efficiency LED TV / display power supplies. The synchronous rectification control extends usable efficiency across the load range, especially at light loads where conventional diode rectification would dominate losses. When designing with the ICE2HS01GXUMA1, ensure the resonant tank (Lr, Lm, Cr) is properly tuned for the application's input voltage range and load profile. Place the bootstrap capacitor close to the high-side driver pin and respect the minimum dead-time requirements to prevent shoot-through. The synchronous rectification outputs must be correctly phased with the secondary-side MOSFETs to avoid body-diode conduction losses.

The device combines a current-mode quasi-resonant controller with a 800V/2.62 ohm (max) MOSFET and a startup cell, switching at a 52 kHz nominal frequency and reaching <100 mW standby power through Active Burst Mode. A quasi-resonant flyback controller is a type of AC-DC switched-mode power supply (SMPS) controller that switches the primary MOSFET near the drain-voltage valley, minimizing turn-on switching losses and EMI. It belongs to the broader class of offline PWM controllers within the power management IC hierarchy, used to convert rectified AC mains into isolated DC voltages for appliances, adapters, and industrial auxiliary supplies. Key features include a 800 V breakdown voltage on the integrated MOSFET, a 10.5 V to 27 V Vcc supply range with 18 V startup threshold, 50% maximum duty cycle, integrated current-mode control, and Active Burst Mode for sub-100 mW standby. The PG-DSO-12-10 package provides a thermally enhanced exposed-pad footprint suitable for 20 W-class auxiliary power designs without external heatsinking. The device uses Infineon's CoolMOS technology with an avalanche-rugged 800V cell, allowing direct rectification of universal AC mains (85-265 VAC) without additional input protection. The quasi-resonant valley-skipping controller adaptively shifts switching frequency based on load, optimizing efficiency across light and full-load conditions. Typical applications include low-power SMPS adapters, white goods auxiliary supplies, standby rails in white goods and TVs, smart meter and IoT device power, and industrial control auxiliary supplies. The 20 W power level makes the part well-suited for always-on appliances requiring ENERGY STAR standby compliance. When designing, ensure transformer leakage inductance is below 5% to prevent MOSFET avalanche overstress, and follow the reference snubber circuit from the manufacturer datasheet. The Vcc capacitor must be sized to sustain 18 V startup and 10.5 V UVLO thresholds under all load transients.

ICE2QS02GXUMA1 - 300W Quasi-Resonant Flyback PWM Controller | Infineon
The Infineon ICE2QS02GXUMA1 is a quasi-resonant (QR) current-mode flyback PWM controller IC in a PG-DSO-8 package, targeting power-conversion applications up to 300 W. It supports a switching frequency range of 20 kHz to 150 kHz, where the controller self-adjusts to the valley of the drain-voltage waveform to minimize switching losses and reduce EMI. The device is part of Infineon's CoolSET family and is designed for quasi-resonant offline flyback converters, offering a blend of high efficiency, low standby power, and integrated protection features. According to Infineon's product brief, the controller is intended for main converters in auxiliary-supplied systems where an external startup cell is unnecessary. A quasi-resonant flyback controller is a type of AC-DC PWM controller that operates the MOSFET in a manner that forces turn-on at a valley of the drain ringing after the transformer demagnetizes. This is a sub-category of current-mode PWM controllers within the broader family of offline AC-DC switching regulators. The quasi-resonant control scheme sits between fixed-frequency hard-switched PWM and full resonant topologies, offering better EMI, lower switching losses, and higher efficiency than hard-switched converters at the cost of a variable frequency that complicates EMI filter design. Key features include a 650 V integrated MOSFET section (typical for CoolSET QR controllers), frequency modulation with active burst mode for ultra-low standby power below 100 mW, and a comprehensive protection set: over-current protection (OCP), over-load protection (OLP), over-voltage protection (OVP), and over-temperature shutdown (OTP). The PG-DSO-8 package offers a compact footprint suitable for dense adapter designs, and the device's start-up behavior and brown-out handling are tailored for 85-265 V AC universal-input applications. The controller uses a current-mode control loop with a built-in transconductance error amplifier. The quasi-resonant valley-switching is achieved by sensing the auxiliary-winding demagnetization time and triggering the next cycle at the detected valley. The 20 kHz minimum switching frequency prevents audible noise, while the 150 kHz maximum frequency cap keeps switching losses manageable. Typical applications include LED lighting drivers up to 150 W, auxiliary power supplies for white goods, and small-format adapters for consumer electronics. The device's ultra-low standby power and QR operation make it especially attractive for ENERGY STAR and EU Ecodesign-compliant products where standby power below 100 mW is mandatory. When designing with this device, ensure the sense resistor on the current-sense pin is sized for the desired OCP threshold and that the gate-drive loop is kept short to avoid parasitic turn-on. The feedback loop compensation should account for the variable switching frequency that is inherent in quasi-resonant operation.

ICE3A2065Z - 650V CoolSET-F3 Offline SMPS Controller | Infineon
The Infineon ICE3A2065Z is an off-line SMPS current-mode controller with an integrated 650V Depletion CoolMOS power switch and 650V startup cell, packaged in a 7-pin PG-DIP-7-1 (through-hole, PDIP-7) housing. It targets flyback topologies at a fixed 100 kHz switching frequency, delivers up to 28 W output power in typical adapter and auxiliary-supply designs, and supports Active Burst Mode for standby power consumption below 100 mW at no load. On-resistance (RDS(on)) is rated at 1.05 ohm maximum at 25 °C, with ESD protection of 3.0 kV HBM. An SMPS current-mode controller with integrated MOSFET is a category of power-supply IC that combines the control loop, gate driver, and high-voltage power switch in a single die. The current-mode architecture regulates the output by sensing peak primary current and comparing it to an error-amplifier-derived threshold on every switching cycle. By integrating the 650V MOSFET and startup cell, the CoolSET-F3 family reduces external component count, simplifies PCB layout, and improves reliability compared with discrete PWM-controller-plus-MOSFET designs. Key specifications include a VCC supply range of 8.5 V to 21 V, quiescent current of 7.1 mA, maximum drain current of 2.0 A pulsed, junction temperature range of -25 °C to 130 °C, and thermal resistance (RthJA) of 96 K/W. The integrated 650V CoolMOS withstands typical 85-265 VAC universal-input offline rectified rails with substantial derating margin. A Current Sense (CS) pin provides cycle-by-cycle peak-current limiting, while the internal current-mode PWM comparator generates the duty cycle from the CS signal and the internal reference ramp. Typical applications include low-power AC-DC adapters (sub-30 W), auxiliary standby supplies in white goods and appliances, DVD/STB standby rails, and low-power LED driver front ends. The wide 85-265 VAC input range and Active Burst Mode make it suitable for designs seeking ENERGY STAR or EuP Tier-2 standby compliance without an additional burst-mode controller IC. When designing with the ICE3A2065Z, size the CS sense resistor for peak primary current at minimum VIN, account for the 96 K/W thermal resistance when laying out PCB copper area, and ensure the VCC hold-up capacitor covers the IC's start-up sequencing before auxiliary winding takes over. Note that the part has reached end-of-life for new designs; Infineon recommends the ICE3A2065ELJ as the active replacement (different pinout and package - PCB rework required).

An AC-DC offline switcher IC of this type combines the power MOSFET and the control IC in one package, enabling compact isolated and non-isolated SMPS designs. In the broader hierarchy, this part belongs to the CoolSET family of integrated power switches, which itself falls under AC-DC converters, which is a sub-category of power management ICs. The integrated approach simplifies flyback converter design for adapters, auxiliary supplies, and standby converters by reducing external component count and PCB footprint. Key features include an integrated 800 V avalanche-rated CoolMOS switch that tolerates harsh line transients, frequency jitter for improved EMI signature, and auto-restart protection for fault conditions. The brownout detection prevents the converter from operating at low input voltages where the transformer can saturate. Active burst mode reduces standby power consumption to well below 100 mW, supporting energy-efficiency regulations. The device operates from a VCC supply of 10.5 V to 25 V and supports a typical flyback power range up to around 15-20 W, depending on thermal design. Internally, the current-mode controller uses a 1.0 V peak-current sense threshold and supports duty cycle up to approximately 75%, enabling wide-range universal-mains operation (85 VAC to 265 VAC). Typical applications include smartphone and tablet chargers, white-goods auxiliary supplies, set-top box standby converters, DVD/Blu-ray auxiliary rails, and industrial metering or IoT gateway power supplies. The 800 V MOSFET rating provides additional safety margin in regions with unstable mains. When designing with this part, pay attention to the snubber network around the integrated MOSFET drain pin to limit voltage overshoot, and select a transformer with adequate primary inductance to keep peak currents within the 1.0 V sense threshold divided by the external sense resistor. This page synthesizes distributor pricing, drop-in alternatives from the CoolSET family, and practical design notes not found in a single manufacturer document.
ICE3AS03LJGXUMA1 - 100kHz CoolSET Flyback PWM Controller | Infineon
The Infineon ICE3AS03LJGXUMA1 is a 100 kHz fixed-frequency current-mode flyback PWM controller with integrated 500 V startup cell, designed for offline AC/DC converters up to 300 W.

The part operates from an 10.5 V to 25 V VCC supply and offers <100 mW standby power for energy-efficient standby operation. A CoolSET AC/DC flyback controller is a self-contained power supply building block that combines a current-mode PWM controller with an internal high-voltage startup transistor and a MOSFET driver on a single monolithic die. By integrating the startup cell, the controller eliminates the external startup resistor chain that would otherwise consume continuous power from the high-voltage rail, dramatically reducing standby losses. The current-mode topology falls within the broader category of switched-mode power supply (SMPS) controllers, which sit hierarchically above linear regulators and below transformer/inductor-based power conversion systems in the power management hierarchy. Key differentiating features include a 500 V integrated startup cell that withstands surge events on rectified mains, active burst mode for sub-100 mW standby power, built-in soft-start to limit inrush current, and frequency jittering for low EMI. The 100 kHz fixed switching frequency is internally trimmed, eliminating external RC timing components. Protection features include over-current protection (OCP), over-load protection (OLP), over-voltage protection (OVP), and VCC under-voltage lockout (UVLO). The auto-restart recovery scheme minimizes external component count while still satisfying safety agency requirements. From an architectural perspective, the ICE3AS03LJG family uses Infineon's 700 V CoolMOS-class technology for the integrated high-voltage section, with a precision current-sense input for cycle-by-cycle peak current control. The internal reference, oscillator, and PWM comparator are trimmed at wafer level for tight frequency tolerance. The current-mode control loop provides inherent input voltage feedforward, simplifying feedback compensation compared to voltage-mode architectures. Typical applications include low-power AC/DC adapters (5 W to 27 W mobile chargers), set-top box auxiliary supplies, LCD TV standby rails, white goods auxiliary power, and any isolated flyback topology requiring sub-100 mW standby consumption. Design considerations should account for the PG-DSO-8 thermal pad connection, the VCC hold-up capacitor sizing for brown-out ride-through, and the use of a Y-cap or transformer shield to meet EMI standards.

The minimum supply voltage VCC min is 10.5 V, enabling robust startup from rectified mains. The integrated 800 V MOSFET eliminates external switch components and provides a compact isolated converter footprint. An SMPS current-mode controller is a power-supply integrated circuit that regulates the output of a switched-mode power supply by sampling both output voltage error and primary-side peak current each switching cycle, then commanding an internal power MOSFET. It belongs to the broader hierarchy of AC-DC converters, flyback controllers, and integrated power management ICs used in offline power designs. This category enables compact isolated power conversion for white goods, adapters, and auxiliary supplies. Key features of the ICE3BR0680JZ include an input brownout detection pin (BBA), active burst mode operation for standby power below 100 mW, extendable blanking time for overload protection, and an external auto-restart enable path. The active burst mode reduces no-load consumption to extremely low standby levels. Internal protection features include overcurrent, overvoltage, overtemperature, and open-loop detection with auto-restart behavior. Typical applications include 40 W isolated flyback adapters, white-goods auxiliary power supplies, DVD/STB standby rails, and industrial low-power offline converters. The wide 800 V drain rating allows universal-mains operation (85-265 VAC) without additional input protection components. Internal current-mode control simplifies loop compensation and provides inherent cycle-by-cycle current limiting. When designing with this device, ensure the VCC reservoir capacitor and BBA blanking-time network values are selected per Infineon application notes. The PG-DIP-7 package provides 7 through-hole pins suitable for wave or hand soldering and allows isolated creepage/clearance per safety standards.
ICE3BR1765JXKLA1 - 650V CoolSET F3R Offline SMPS | Infineon
The Infineon ICE3BR1765JXKLA1 is an integrated AC-DC power stage from the CoolSET F3R family that combines a 650 V CoolMOS power MOSFET with a fixed-frequency current-mode PWM controller in a single 8-pin PG-DIP-8 through-hole package. The integrated MOSFET is specified at VDS max of 650 V and RDS(on) max of 1.96 ohm, while the controller block runs at a fixed switching frequency of 65 kHz and supports a maximum output power of 25 W in flyback topology. The VCC supply range spans 10.5 V to 25 V, enabling broad input mains coverage including universal 85-265 VAC offline converters. A flyback converter is the most common topology for low-to-medium power isolated AC-DC switching power supplies, where the transformer's primary inductance stores energy during the MOSFET on-time and transfers it to the secondary during the off-time. The integrated power-stage approach (CoolSET) eliminates the need for an external MOSFET, gate driver, and many discrete protection parts - reducing BOM count, PCB area, and overall system cost for sub-25 W applications. This category sits within AC-DC converters -> power management ICs -> semiconductor devices. Key features include built-in 650 V avalanche-rated CoolMOS, integrated soft-start, frequency jittering for low EMI, auto-restart protection for open-loop, VCC overvoltage, overload, and overtemperature faults. The 65 kHz fixed frequency keeps the fundamental switching noise out of the AM radio band and simplifies input EMI filter design. The PG-DIP-8 package provides 8 mm of creepage distance between high-voltage drain pins and low-voltage signal pins, which is critical for offline safety isolation. Typical applications include mobile phone chargers, standby auxiliary supplies for white goods and TVs, DVD player standby rails, and any sub-25 W isolated AC-DC adapter or auxiliary SMPS. The universal VCC range also supports wide-input industrial auxiliary supplies. When designing with this device, ensure the snubber network across the transformer's primary leakage inductance is properly sized to keep the drain voltage spike below the 650 V BVDSS rating.

The Infineon ICE3RBR0665JZXKLA1 is an off-line SMPS current-mode controller IC with an integrated 650V CoolMOS power switch and an integrated start-up cell, housed in a 7-pin PG-DIP-7-1 (DIP-7) through-hole package. It combines a PWM controller, a 650V MOSFET, and start-up circuitry in one IC, reducing component count for isolated AC/DC flyback converters. The fixed switching frequency is 65 kHz, and the breakdown voltage of the integrated CoolMOS is 650V, enabling universal-input offline designs from 85VAC to 265VAC. A current-mode PWM controller is a control IC that regulates output by sensing the current through the main power switch on a cycle-by-cycle basis, providing inherent peak-current limiting and simplified loop compensation. Within the broader taxonomy, an SMPS controller falls under AC-DC converters -> power management IC -> semiconductor. The CoolSET family further integrates the high-voltage MOSFET into the same package, which makes it distinct from controllers that require an external FET and from fully integrated modules. Key features of the ICE3RBR0665JZXKLA1 include a 650V integrated CoolMOS with a maximum on-resistance per the CoolSET F3R family datasheet, a 65 kHz fixed switching frequency, auto-restart protection for open-loop, VCC overvoltage, and overload faults, and an extended operating temperature range down to -40C. According to the manufacturer datasheet, the VCC supply range is 10.5V to 25V and the duty cycle maximum is 75%, supporting compact adapter and auxiliary-supply designs. Typical applications include low-power AC/DC adapters (smartphone chargers, set-top boxes, DVD players), standby and auxiliary supplies for white goods and industrial equipment, and isolated auxiliary rails in motor drives and metered appliances. The integrated start-up cell eliminates external bleeder resistors and reduces standby power, while the integrated 650V switch withstands universal mains transients. When designing with this part, designers must observe the VCC start-up threshold (18V typical) and select a VCC hold-up capacitor sized for the desired burst-mode entry threshold. The PG-DIP-7-1 package provides adequate creepage for reinforced isolation when paired with a through-hole transformer construction. Designers should follow the Infineon CoolSET design guide for snubber and RCD clamp values.

The Infineon ICE3RBR1765JGXUMA1 is a 650V breakdown-voltage offline flyback AC-DC converter and switching controller integrated in a PG-DSO-12-19 (DSO-16/12) surface-mount package. It operates at a nominal switching frequency of 65 kHz (datasheet maximum 67.6 kHz), supports a 10.5 V to 25 V Vcc supply range, and delivers up to 75% maximum duty cycle. The IC combines a 650 V power MOSFET with current-mode PWM control to drive isolated and non-isolated flyback converters directly from rectified mains. An AC-DC offline switching converter is a power-management IC that converts rectified AC mains (typically 85-265 VAC) into one or more regulated DC output rails using a flyback transformer topology. The CoolSET family from Infineon integrates the high-voltage power switch, current-sense controller, and protection logic into a single monolithic device, replacing discrete implementations that require separate PWM controllers and external MOSFETs. Within the broader power-management hierarchy, the CoolSET sits between primary-side controllers and fully integrated modules (DC-DC converters), targeting low-to-medium-power SMPS designs. Key features include BiCMOS technology with active burst mode for ultra-low standby power (well below 100 mW), built-in frequency jitter to ease EMI compliance, soft gate driving to limit switching losses, propagation-delay compensation for accurate duty-cycle control, built-in soft-start, and extendable blanking time for overload protection. An external auto-restart enable pin provides flexible fault recovery. These integrated features reduce external BOM count by typically 15-20 components versus discrete implementations. The device uses a BiCMOS process node optimized for high-voltage switching, pairing a 650V-rated MOSFET drain with low-power CMOS control logic. Current-mode control provides inherent cycle-by-cycle current limiting and simplified feedback loop compensation compared to voltage-mode control. Frequency jitter spreads switching noise spectrum to ease conducted EMI filtering requirements. Typical applications include auxiliary supplies for white goods and home appliances, standby power for TVs and set-top boxes, low-power adapters, and industrial control board housekeeping rails. The active burst mode enables energy-star compliance with standby power typically below 100 mW. When designing, ensure adequate Vcc hold-up capacitance to ride through short mains dropouts and verify transformer leakage inductance is below 5% of primary inductance to prevent avalanche stress on the integrated 650V MOSFET.

The PG-DSO-8 package provides a low thermal resistance path, supporting continuous operation at elevated ambient temperatures. From an architectural standpoint, the device uses a current-mode control scheme with leading-edge blanking to suppress transformer leakage spike false tripping. The integrated 800V MOSFET allows direct connection to a rectified 230V AC mains without an external depletion-mode start-up device, simplifying the bill of materials. The PG-DSO-8 package is pin-compatible with the wider CoolSET ICE2/ICE5 family, enabling PCB layout reuse across power-rating variants. Typical applications include 5W to 15W AC/DC adapters for white goods and consumer electronics, standby and auxiliary power supplies for major home appliances, LED lighting drivers, and metering power supplies. The 800V MOSFET rating provides sufficient voltage margin for universal AC input (85V to 265V AC) designs. When designing with this device, ensure the transformer primary inductance and snubber network are sized for the chosen switching frequency and maximum duty cycle. The exposed pad must be soldered to a sufficient copper pour for thermal dissipation, and VCC hold-up capacitance must be sized to ride through short brown-out events without the controller re-entering start-up.

It is a power-supply controller that regulates energy transfer in a flyback (isolated buck-boost) topology by switching the primary of a coupled inductor at fixed frequency, where the controller and high-voltage switch are monolithically combined in a single SO-8/DPAK-style package. In the broader taxonomy, it is a sub-class of switched-mode power supply (SMPS) controllers, which sit under power management ICs and serve as the core of isolated AC-DC converters used in adapters, open-frame power supplies and auxiliary supplies. Key features of the ICE5ASAGXUMA1 include 100 kHz maximum switching frequency, 700V integrated MOSFET breakdown voltage, 9.4V to 27V VCC operating range (with brown-in protection), and comprehensive protection suite: overload, over-temperature, VCC over/under-voltage, open-loop, and output over-voltage protection. The 3-level selectable entry/exit threshold lets designers trade standby power against immunity to mains dips. Technically, the device uses current-mode control with a precise internal reference, supporting both quasi-resonant-like valley skipping and fixed-frequency operation. The integrated cascode startup stage eliminates the external startup resistor network, shrinking the BOM and improving no-load consumption. Typical applications include low-power AC-DC adapters (5W-15W), auxiliary supplies for white goods and industrial equipment, standby SMPS for set-top boxes, and isolated LED drivers. When designing with this part, ensure that the VCC capacitor value is sized per the Infineon demoboard reference and that the CS pin current-sense resistor handles peak primary current with adequate margin.

The IC implements digital frequency reduction, cycle-by-cycle peak current limitation, selectable active burst mode, digital soft-start, and cascode-configured rapid startup. A quasi-resonant CoolSET is a class of monolithic AC/DC switcher that combines a high-voltage MOSFET and a current-mode controller in one package, allowing the engineer to design an isolated or non-isolated flyback converter with minimal external components. The CoolSET family belongs to the broader category of AC/DC converters and offline switchers, sitting inside the power-management IC hierarchy used in SMPS (switched-mode power supply) designs. The QR (quasi-resonant) variant forces the MOSFET to turn on at the valley of the drain-voltage ringing, reducing switching losses and EMI compared to hard-switched DCM converters. Key features include a 700 V / 800 V integrated P7 MOSFET with 0.8 Ω maximum on-resistance, 2-level selectable active burst mode for light-load efficiency, line-input over-voltage and brown-in/out protection, VCC short-to-ground protection, output over-load protection (OLP), and output-short protection.

The high-rail breakdown voltage (800 V) provides wide margin on 265 V AC rectified mains and improves surge robustness on Indian and Brazilian grids. When designing with this CoolSET, ensure the VCC capacitor and auxiliary winding supply keep VCC within 10.5 V to 24 V across all load steps, and respect the SOA of the integrated MOSFET at high line and peak loads. Mount the exposed pad on sufficient copper (≥ 1 sq inch recommended) to keep the junction below 125 °C at 42 W continuous output.
ICE5QSBGXUMA1 - 27W QR Flyback PWM Controller | Infineon
The Infineon ICE5QSBGXUMA1 is a 5th-generation quasi-resonant (QR) flyback PWM controller in the CoolSET family, integrating a 750 V CoolMOS MOSFET and PWM control circuitry into a single PG-DSO-8 package. It is engineered for offline AC/DC switched-mode power supplies targeting auxiliary supplies, smart meters, and low-power adapters up to approximately 27 W. The controller operates from a wide VCC range and uses valley switching for low EMI and high efficiency across load. A flyback converter is the dominant topology for low-to-medium power isolated AC/DC supplies because it provides galvanic isolation and multiple outputs with a single magnetic element. Quasi-resonant control improves on hard-switched PWM by switching the MOSFET on at the drain-source voltage valley, which reduces switching losses and EMI. The CoolSET product line from Infineon packages this QR controller plus the high-voltage power MOSFET into a single IC, eliminating the need for a separate switch and shrinking the BOM. Key features include integrated 750 V MOSFET, quasi-resonant valley switching, built-in soft-start, frequency reduction at light load, and a comprehensive protection suite that covers over-current, over-voltage, over-temperature, overload, open-loop, and VCC under-voltage. The device is targeted at universal-input (85 V to 265 V AC) designs with > 82 percent typical efficiency, simplifying EN 62368-1 and Energy Star compliance for white goods and industrial auxiliary rails. The ICE5QSBG uses current-mode control with cycle-by-cycle current limiting and a 65 kHz base switching frequency. Frequency foldback at low load reduces switching losses and improves light-load efficiency to meet EuP/CoC Tier 2 standby targets below 75 mW. The IC supports burst-mode operation for sub-100 mW standby, which is critical for always-on appliances. Typical applications include 5 V to 12 V auxiliary supplies for white goods and major appliances, smart-meter and IoT gateways, bias supplies for industrial PLCs, set-top box standby rails, and small open-frame adapters for lighting controls. The PG-DSO-8 footprint with high-voltage clearance makes it suitable for through-hole or SMD layouts where PCB creepage must exceed 6 mm. When designing with this controller, allow adequate creepage between the DSO-8 package and any low-voltage secondary traces to satisfy IEC 62368-1. The VCC hold-up capacitor value must be sized so that VCC never collapses below UVOFF during start-up under worst-case AC line conditions. Place the current-sense resistor close to the SOURCE pin to minimize parasitic inductance in the gate-drive return path.

A buck converter reduces a higher input voltage to a lower output voltage using a controlled switch, an inductor, and a rectifier. By integrating the high-side and low-side MOSFETs, the IP6537 shrinks the BOM versus discrete buck designs and improves efficiency, typically reaching the mid-90% range at moderate loads. Internally, the device combines a peak-current-mode buck controller with adaptive gate-drive timing and a PD protocol state machine. Built-in line-drop compensation maintains accurate output voltage under varying cable loads, while the integrated NMOS charge-pump drives the high-side switch reliably across the 6 V-32 V input range. This architecture supports constant-voltage (CV) and constant-current (CC) modes required by USB PD 3.0 PPS-style adapters. Typical applications include 20 W USB-C PD wall chargers, multi-protocol fast-charging adapters (PPS, QC), portable power banks, and 5 V-12 V auxiliary supplies in industrial equipment.

IPD3019-760S - 19V 30W Desktop AC/DC Adapter | Inventus Power
The Inventus Power IPD3019-760S is a 30 W external desktop AC/DC adapter delivering a regulated 19 VDC output at up to 1.58 A through a 5.5 mm x 2.1 mm barrel connector. It is a Class I grounded desktop form factor, accepting a detachable IEC 60320 C14 power inlet cord (sold separately) and providing a single regulated output suitable for a wide range of 19 V nominal equipment. What is an external desktop AC/DC adapter? An external desktop AC/DC adapter (also called a "wall wart" desktop variant) is a self-contained off-line power supply housed in a plastic enclosure that sits on the desktop and converts the AC mains (100-240 VAC, 50/60 Hz) into a single low-voltage DC output. It is the product taxonomy of: AC/DC adapter -> external power supply -> power supply -> power management -> electronic component. Desktop adapters differ from wall-mount adapters in their larger size, higher power capability (typically 15-150 W), use of a Class I earthed inlet for higher safety/EMI margins, and reliance on a detachable mains cord so the same adapter can be shipped to multiple regional markets simply by changing the cord. Key features of the IPD3019-760S include a universal 100-240 VAC input range (with appropriate detachable cord set), a tightly regulated 19 VDC output at 1.58 A (30 W continuous), over-current / over-voltage / short-circuit protection per the Inventus Power adapter family platform, and a 5.5 x 2.1 mm coaxial barrel output jack. The "S" suffix designates the specific barrel connector option within the IPD3019 family. Class I grounding provides a chassis/earth ground path that improves EMI performance and user safety compared with Class II double-insulated wall-mount units of similar rating. Architecturally, the IPD3019-760S is built on Inventus Power's proven off-line flyback converter platform with primary-side regulation, secondary-side synchronous rectification, and an optocoupler-based feedback loop. The platform typically achieves >85% average efficiency at nominal line and >80% efficiency at low line, comfortably meeting the DoE Level VI efficiency requirements that govern external power supplies. The unit operates at a switching frequency that keeps fundamental switching noise outside of AM broadcast bands and provides adequate margin for conducted and radiated EMI compliance per EN 55022 Class B. Typical applications include powering 19 VDC LCD monitors, small form-factor POS terminals, 19 VDC industrial test equipment, networking gear requiring a 19 V brick, single-board computer and embedded development kits, and as a direct OEM replacement for equipment originally shipped with a 19 V 30 W desktop supply. It is a common replacement SKU for end-of-life or damaged Inventus Power supplies in field-deployed equipment. When designing with this adapter, plan for a ventilation clearance of at least 2 inches around the enclosure because the unit dissipates 5-7 W internally at full load. Verify that the load's maximum draw is below 1.58 A continuous and that the load's input voltage tolerance includes 19 V +/- 5%. Use only a detachable cord set rated for the regional mains standard.

The Infineon IR38062MTRPBF is a 15 A single-input synchronous digital SupIRBuck buck regulator with a PMBus interface, housed in a 34-pin PQFN (5 x 7 mm) package. It integrates high-side and low-side MOSFETs plus an internal LDO that enables single 21 V operation, eliminating the need for a separate bias supply. The output voltage is adjustable from 0.5 V up to 0.875 x PVin (max 18.375 V) with 0.5 percent reference accuracy, and the switching frequency is programmable from 400 kHz to 1.5 MHz using the Rt/Sync pin or the PMBus digital interface. A buck regulator (also called a step-down DC-DC 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 input across an inductor and filtering the result. It belongs to the broader category of voltage regulators within power management ICs and is preferred over linear regulators whenever the input-to-output voltage differential is large, because switching conversion avoids the heavy thermal losses inherent to linear dropout regulation. Digital SupIRBuck regulators add PMBus telemetry and configuration on top of the analog PWM control loop. Key features of the IR38062MTRPBF include 15 A continuous output current, 0.5 percent reference accuracy, programmable switching frequency up to 1.5 MHz, internal soft-start, and comprehensive protection such as overcurrent, overvoltage, undervoltage, and thermal shutdown. The PMBus interface exposes voltage, current, temperature, and fault status registers, while the Rt/Sync pin allows the converter to be synchronized to an external clock or another regulator for multi-phase or noise-sensitive applications. Technically, the IR38062 uses voltage-mode control with a wide-bandwidth error amplifier, an integrated bootstrap diode, and per-cycle current limit on the low-side FET to deliver robust transient response. The 34-pin PQFN package exposes a large thermal pad to keep junction temperature rise within safe limits at full 15 A load, and the digital core allows designers to trim margining, sequencing, and fault thresholds in-circuit via PMBus without replacing components. Typical applications include POL (point-of-load) converters in telecom and networking equipment, FPGA and ASIC core/IO rails in servers and datacenters, industrial automation controllers, graphics cards, and any distributed power architecture that requires digital monitoring and tight regulation across multiple rails. When designing with this part, place input ceramic capacitors as close as possible to PVin and PGND, use the recommended inductor with low DCR for high efficiency, and connect the PMBus lines (SCL, SDA, SALERT) to a system controller for telemetry. Ensure adequate PCB copper on the thermal pad for 15 A continuous operation without exceeding the maximum junction temperature.

IR38063MTRPBF - 25A Digital SupIRBuck PMBus POL | Infineon
The Infineon IR38063MTRPBF is a 25 A single-input synchronous buck regulator with PMBus digital interface, housed in a 34-pin PowerVFQFN (5x7 mm) package. It accepts an input voltage range of 5.5 V to 21 V and produces an adjustable output from 0.5 V to 0.875×PVin (up to 18.375 V) with 1% set-point accuracy, making it one of the highest-current density digital point-of-load (POL) converters in the SupIRBuck family. Integrated MOSFETs, a 5.2 V internal LDO bias, and PMBus telemetry for Vout/Iout/Temperature deliver a complete digital power solution in a compact footprint. A buck converter (step-down switching regulator) is a DC-DC converter topology that uses an internal high-side switch, low-side synchronous rectifier, and an LC output filter to produce a regulated lower voltage from a higher input rail. The synchronous variant replaces the traditional diode with a low-RDS(on) MOSFET to maximize efficiency. In the power management hierarchy, buck regulators sit under DC-DC converters, which in turn belong to the broader power management IC family. Digital POL converters extend this category with serial bus telemetry and programmability for adaptive voltage scaling, fault logging, and margining in advanced computing platforms. Key features of the IR38063MTRPBF include 25 A continuous output current, ±1% reference accuracy over line/load/temperature, internal current sensing with no external shunt resistor, and a switching frequency range of 200 kHz to 1.5 MHz selectable via an external resistor. Protection features include over-current (OCP), over-voltage (OVP), under-voltage (UVP), and over-temperature (OTP) protection with PMBus fault reporting. The 5x7 mm PQFN package exposes the die through a thermal pad, achieving a junction-to-ambient thermal resistance around 20 C/W with proper PCB layout. The IR38063 uses voltage-mode control with an internal MOSFET gate driver optimized for sub-100 ns transition times. The integrated bootstrap supply eliminates the external bootstrap diode, and the LDO output is brought out at Vcc for external decoupling. The result is a converter that can deliver 25 A at 1.0 V out from 12 V in at greater than 90% efficiency, with PMBus-readable Vout, Iout, and temperature telemetry enabling closed-loop adaptive voltage scaling in ASICs, FPGAs, and network processors. Typical applications include server and storage point-of-load regulation, networking ASIC and FPGA core rails, telecom base-station digital cards, and high-end computing motherboards. The PMBus interface makes it ideal for platforms requiring in-system monitoring, dynamic voltage scaling, or N+1 redundancy, where the system controller continuously polls the part's telemetry to optimize power and thermal behavior. When designing with this device, pay close attention to PCB layout: the input capacitors must be placed within 2-3 mm of the PVin and PGND pins, and the exposed pad requires a thermal via array to inner copper planes. A minimum of 2 oz copper on inner layers is recommended for full 25 A operation without thermal throttling, and the PMBus pull-up resistors should be sized according to the bus capacitance to ensure signal integrity at 400 kHz.

The integrated SVID interface enables Intel-compatible VR core rail implementations without external controllers, while I2C/PMBus allows real-time telemetry of output voltage, current, and temperature. The on-chip PWM controller uses voltage-mode control with selectable switching frequency, and the device integrates protection features including over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), over-temperature protection (OTP), and pre-bias startup. Telemetry parameters (VOUT, IOUT, temperature) are accessible via PMBus. The PowerVFQFN package provides a top-side thermal pad that is soldered directly to PCB copper to achieve the rated 30A continuous current without external heatsinks in properly designed boards. Typical applications include Intel VR core rails in servers, workstations and high-end desktops, ASIC and FPGA core supplies, high-current point-of-load (POL) converters in networking switches and routers, and DDR memory VDDQ termination supplies in datacom equipment. The combination of high current, small footprint, and digital interface makes it well suited for space-constrained, high-density power designs. When designing with this device, allocate sufficient PCB copper area beneath the exposed thermal pad and use the manufacturer's recommended inductor and capacitor selection to maintain ripple within 1% of VOUT.
