PFS7538H

Overview

The PFS7538H is a Power Factor Correction (PFC) controller from the HiperPFS-3 family, designed for continuous conduction mode (CCM) applications. It supports a peak power output of 900 W with an input voltage range of 180 VAC. The device operates within a switching frequency range of 22 kHz to 123 kHz and requires a supply voltage between 10.2 V and 15 V. It is housed in a 16-SSIP, 13-lead package with a bare pad, designated as eSIP-16D, and functions reliably across a temperature range of -40°C to 150°C.

Feature Summary

• Integrated CCM PFC control with variable frequency operation
• High-voltage startup circuitry for simplified design
• Comprehensive protection features including overvoltage and thermal shutdown

Applications

• High-power AC/DC adapters
• Server and telecom power supplies
• Industrial power systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct pinout and electrical characteristics. Confirm RoHS compliance status and check for any recent Product Change Notifications or End-of-Life announcements prior to finalizing procurement plans.

Selection Notes

Select this component for designs requiring high-efficiency PFC at peak powers up to 900 W. Ensure the application environment supports the specified operating temperature range and that the PCB layout accommodates the eSIP-16D package dimensions and thermal requirements.

Part Context

Part of the HiperPFS-3 series, which integrates PFC and secondary-side regulation capabilities. This model represents a higher power variant within the family, suitable for demanding applications where size reduction and efficiency are critical priorities compared to discrete solutions.

Replacement Considerations

Consult official substitution lists for direct equivalents within the HiperPFS-3 family. Verify pin compatibility and thermal performance when considering alternative part numbers from other manufacturers.
