PFS7629H

Overview

The PFS7629H is a power factor correction controller from Power Integrations featuring an integrated 600 V MOSFET. It operates in continuous conduction mode with a switching frequency range of 22 kHz to 123 kHz. The device supports input voltages up to 450 VAC and delivers output power ratings between 405 W and 450 W. It utilizes an eSIP-16D package for through-hole mounting, ensuring high efficiency and power factor across the load range.

Feature Summary

• Integrates a 600 V MOSFET within a single component
• Optimized for high efficiency and power factor across varying loads
• Features EMI optimization through spread spectrum technology
• Includes brown-in/brown-out detection and under-voltage lockout

Applications

• High-power AC/DC power supplies
• Industrial power conversion systems
• Battery chargers requiring high power factor

Procurement Notes

Verify the specific suffix and package variant against official datasheets before ordering. Confirm that the eSIP-16D through-hole form factor matches the target PCB layout. Ensure thermal management requirements align with the integrated MOSFET capabilities. Cross-reference manufacturer part numbers to avoid counterfeit components.

Selection Notes

Select this component for designs requiring high power density without external gate drivers. The integrated 600 V FET simplifies bill of materials. Consider the 123 kHz maximum frequency for transformer sizing. Evaluate thermal performance given the high power handling in the SIP package.

Part Context

This part belongs to the HiperPFS family of power factor correction controllers. It combines control logic with a high-voltage switch to reduce component count. The series targets applications demanding strict power quality standards and compact form factors.

Replacement Considerations

Direct substitutes include other HiperPFS models with similar voltage ratings and pinouts. Verify compatibility with existing magnetics when swapping variants.
