PFS7528H

Overview

The PFS7528H is a HiperPFS-3 family power factor correction controller designed for continuous conduction mode (CCM) boost applications. It integrates a high-voltage startup circuit, a 600 V power MOSFET, and a gate driver within a single eSIP-16D package. The device supports a peak output power of 385 W with a minimum input voltage of 90 VAC. Operating frequencies range from 22 kHz to 123 kHz, ensuring compliance with electromagnetic interference standards through spread spectrum modulation.

Feature Summary

• Integrates a 600 V power MOSFET and gate driver in a low-profile eSIP-16D package
• Supports continuous conduction mode (CCM) boost power factor correction
• Includes an internal high-voltage startup circuit eliminating external components
• Features spread spectrum modulation to minimize electromagnetic interference filtering requirements

Applications

• Power supplies for personal computers and printers
• LCD television sets
• Video game consoles
• High-power adapters and USB PD chargers
• Industrial control systems and home appliances

Procurement Notes

Verify the specific suffix 'H' indicates the correct package variant during procurement. Confirm RoHS compliance status via the manufacturer's official documentation before integration. Ensure the ordering quantity aligns with standard tube packaging constraints provided by authorized distributors. Cross-reference the manufacturer part number against current datasheets to validate revision levels.

Selection Notes

Select this component for designs requiring integrated CCM PFC solutions up to 385 W peak power. The device is suitable for universal input ranges starting at 90 VAC. Consider the thermal performance of the eSIP-16D package for heat dissipation requirements. Verify that the application does not exceed the maximum operating temperature of 150°C under worst-case conditions.

Part Context

The PFS7528H belongs to the HiperPFS-3 series, which combines a PFC controller, gate driver, and power MOSFET into a single monolithic IC. This integration reduces the bill of materials and simplifies layout compared to discrete solutions. The series targets high-efficiency power factor correction for medium-power AC/DC conversion applications.

Replacement Considerations

Consult the official Power Integrations replacement guide for verified substitutes. Check for pin-compatible alternatives within the same HiperPFS family or updated generations. Ensure electrical parameters such as breakdown voltage and switching frequency remain compatible with the existing design.
