PFS7629H/L

Overview

The PFS7629H/L is a Power Factor Correction (PFC) controller from the HiperPFS-4 family, designed for high-performance power supplies. It integrates a 600V MOSFET and operates at a switching frequency of 123 kHz. The device supports input voltages starting from 90 VAC and delivers output power ratings of 405W or 450W depending on the specific variant. It utilizes an eSIP-16D package for compact surface-mount installation.

Feature Summary

• Integrates a high-voltage 600V MOSFET with the control logic to reduce component count
• Provides high power factor correction performance across wide input voltage ranges
• Features fixed-frequency operation at 123 kHz for optimized magnetic component design

Applications

• High-power LED lighting drivers
• Computer peripheral power supplies
• Telecommunications equipment power systems

Procurement Notes

Verify the exact suffix (H or L) against the Bill of Materials, as variants differ in power rating. Confirm the eSIP-16D package compatibility with PCB footprints. Check moisture sensitivity levels for reflow soldering profiles. Ensure the selected variant matches the required 405W or 450W output specification for the target application.

Selection Notes

Select this component for applications requiring integrated PFC and high efficiency without external discrete switches. Compare the 405W and 450W variants based on thermal management capabilities and input voltage requirements. Consider the 123 kHz switching frequency when designing transformer and inductor specifications for EMI compliance.

Part Context

This part belongs to the HiperPFS-4 family of integrated power factor correction controllers. It combines the benefits of boundary conduction mode control with a high-voltage integrated switch. The series is known for reducing solution size and cost in medium-to-high power applications compared to discrete solutions.

Replacement Considerations

Direct substitutes within the same family include other HiperPFS-4 variants with similar power ratings. Verify pinout compatibility and thermal characteristics before swapping. Cross-reference with older HiperPFS generations only if pin-compatible and electrical parameters are strictly matched.
