PFS7624H

Overview

The PFS7624H is a Power Factor Correction (PFC) controller from the HiperPFS-3 series by Power Integrations. It integrates a continuous conduction mode (CCM) boost PFC controller, gate driver, and power MOSFET in a single low-profile eSIP-16 package. The device operates with a switching frequency of 60 kHz and supports a supply voltage range of 5V to 12V. It is designed for surface mount installation and functions within an operating temperature range of -40°C to +150°C.

Procurement Notes

Verify the specific suffix (e.g., H vs L) against the official datasheet to ensure correct pinout and thermal characteristics. Confirm RoHS compliance status through manufacturer documentation. Check for end-of-life notifications or discontinuation notices prior to final design approval. Ensure component authenticity via authorized distribution channels.

Selection Notes

Select this component for designs requiring integrated PFC and MOSFET functionality in a compact form factor. Consider the 60 kHz switching frequency for EMI management. Evaluate the 150°C maximum junction temperature for high-temperature environments. Compare peak power capabilities against system requirements to ensure adequate headroom.

Part Context

The PFS7624H belongs to the HiperPFS-3 family, which combines PFC control with power switching in a single IC. This integration reduces component count and board space compared to discrete solutions. The series is known for high efficiency and simplified design implementation for medium-power applications.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Verify pin compatibility and electrical parameters before substitution.
