PFS7626H/L

Overview

The PFS7626H/L is a HiperPFS-4 device integrating a continuous conduction mode boost power factor correction controller, gate driver, and 600 V power MOSFET. It utilizes an innovative control technique that adjusts switching frequency based on output load, input line voltage, and input line cycle to maximize efficiency across the entire load range. The component eliminates external current sense resistors, reducing associated power loss. It features advanced digital techniques for line monitoring and feed-forward scaling, alongside analog core control for low no-load consumption.

• Office equipment power adapters

Procurement Notes

Verify the specific suffix (H or L) against the official datasheet to confirm pinout and thermal characteristics. Confirm RoHS compliance status with the manufacturer. Ensure the selected package variant matches the PCB footprint requirements. Validate operating temperature ranges against application constraints.

Selection Notes

Select this component for applications requiring high power factor and efficiency without external current sensing. Consider the integrated 600 V MOSFET rating for voltage stress. Evaluate the thermal performance of the eSIP package for the target power level. Verify compatibility with dimmable LED loads if applicable.

Part Context

The PFS7626H/L belongs to the HiperPFS-4 family from Power Integrations. This series is designed for mid-to-high power AC-DC conversion. It replaces previous generations by offering improved efficiency at light loads and reduced component count through integration.

Replacement Considerations

Check for direct pin-compatible upgrades within the HiperPFS-4 family. Verify if older HiperPFS-3 devices meet the efficiency requirements. Ensure any substitute supports the required 600 V rating and CCM operation.
