PFS7535H

Overview

The PFS7535H is a Power Factor Correction (PFC) controller from the HiperPFS-3 family, designed for continuous conduction mode (CCM) operation. It features a variable switching frequency ranging from 22 kHz to 123 kHz. The device operates with a supply voltage between 10.2 V and 15 V and supports an input AC voltage range of 90 V to 265 V. It delivers a maximum output voltage of 385 V DC and can handle a peak output current of 11.3 A. The component is housed in a 16-SSIP, eSIP-16D package with a bare thermal pad for through-hole mounting.

Feature Summary

• Integrated CCM PFC control with variable frequency operation
• Built-in protection mechanisms including over-voltage and over-current safeguards
• High integration level reducing external component count
• Thermal management via exposed pad for efficient heat dissipation

Applications

• Power supplies for personal computers and printers
• LCD television power stages
• Video game consoles
• Industrial control systems
• Home appliances requiring high power factor correction

Procurement Notes

Verify the specific suffix 'H' corresponds to the eSIP-16D package variant. Confirm RoHS compliance status matches REACH regulations. Check end-of-life notifications against the April 2026 PCN data. Ensure ordering quantities align with standard tube packaging requirements.

Selection Notes

Select this component for designs requiring CCM PFC with wide input voltage ranges. Consider the thermal performance of the eSIP-16D package for high-power applications. Evaluate the variable frequency range for EMI filter design compatibility. Verify that the 385 V output voltage capability meets system requirements.
