PFS7324H

Overview

The PFS7324H is a high-power power factor correction (PFC) controller manufactured by Power Integrations. It features an integrated high-voltage MOSFET and utilizes eSIP-16D packaging for through-hole installation. The device supports an input voltage range of 90 to 265 V AC, with a typical operating voltage of 230 V AC. It delivers a maximum output voltage of 385 V DC and can handle a maximum output current of 15.8 A. The unit includes an 8.8 A current limit protection feature. It operates within a temperature range of -40 °C to +150 °C and measures 16.59 x 2.06 x 8.25 mm.

Feature Summary

• Integrates a high-voltage MOSFET with the PFC controller for compact design
• Utilizes eSIP package technology for efficient thermal management
• Includes built-in system monitoring and device protection mechanisms

Applications

• High power density power supplies
• Server and storage systems
• Telecommunications equipment

Procurement Notes

Verify the specific suffix code against official datasheets to confirm pinout and electrical characteristics. Ensure compatibility with existing PCB footprints for the eSIP-16D package. Confirm RoHS compliance status if required by regional regulations. Cross-reference manufacturer part numbers to avoid counterfeit components.

Selection Notes

Select this component for applications requiring high efficiency and power density in AC-DC conversion stages. The integrated MOSFET reduces external component count compared to discrete solutions. Consider the thermal performance of the eSIP package for high-temperature environments. Verify that the 385 V DC output rating aligns with downstream converter requirements.

Part Context

This part belongs to the PFS73xx series from Power Integrations, designed for high-power PFC applications. The series integrates control logic with power switching elements to simplify design. These controllers are commonly used in industrial and commercial power supply designs where size and efficiency are critical constraints.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as other variants in the PFS73xx series. Verify that any substitute maintains the same eSIP-16D footprint and thermal characteristics. Ensure equivalent electrical ratings for voltage and current limits.
