PFS7635H

Overview

The PFS7635H is a HiperPFS-4 device integrating a continuous conduction mode (CCM) boost power factor correction controller, gate driver, and a 600 V power MOSFET into a single compact eSIP-16D package with an internally connected ground pin. It supports switching frequencies from 22 kHz to 123 kHz and operates with a supply voltage of 10.2 V to 15 V. The component delivers up to 480 W peak power and 435 W rated power at 180 VAC input. It functions within an operating temperature range of -40 °C to 125 °C.

Feature Summary

• Integrates CCM boost PFC controller, gate driver, and 600 V power MOSFET in one package
• Eliminates the need for external discrete components typically required for PFC stages
• Features an internally connected ground pin within a thin power footprint

Applications

• Power factor correction stages in AC/DC adapters
• Flyback converter primary side control
• LED lighting drivers requiring high power factor

Procurement Notes

Verify the specific suffix 'H' corresponds to the tube packaging configuration as indicated by distributor listings. Confirm that the eSIP-16D footprint matches your PCB design requirements. Ensure the selected variant meets the required thermal management specifications for the intended 480 W peak power application environment.

Selection Notes

Select this component when designing high-efficiency power supplies requiring integrated PFC and flyback functionality. The HiperPFS-4 family offers reduced bill of materials due to integration. Consider the 600 V MOSFET rating for standard universal input voltages. Verify compatibility with the target output power levels of 435 W to 480 W.

Part Context

The PFS7635H belongs to the HiperPFS-4 series from Power Integrations. This series combines power factor correction and primary-side regulation in a single IC. It targets applications needing high power density and efficiency without complex external control loops or multiple discrete switches.

Replacement Considerations

Check for HiperPFS-4 variants with different power ratings or package options if system constraints differ. Verify electrical compatibility before substituting with older HiperPFS generations.
