PFS7525H

Overview

The PFS7525H is a Power Factor Correction (PFC) controller from the HiperPFS-3 family by Power Integrations. It operates in Continuous Conduction Mode (CCM) with a switching frequency range of 22 kHz to 123 kHz. The device supports a peak power output of 400 W at 90 VAC input. It utilizes an eSIP-16D package for through-hole mounting, featuring a supply voltage range of 10.2 V to 15 V and an operating temperature range of -40°C to 150°C.

Feature Summary

• Integrates CCM boost PFC control with gate driver and power MOSFET
• Eliminates external current sense resistors to reduce power loss
• Adjusts switching frequency over load and line voltage for efficiency optimization
• Features spread spectrum effect to minimize EMI filtering requirements

Applications

• High-power adapters
• LCD televisions
• Industrial controls
• Home appliances

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's datasheet to confirm pinout and thermal characteristics. Confirm RoHS compliance status via official documentation. Check for end-of-life notices or product change notifications prior to final design approval.

Selection Notes

Select this component for designs requiring high-efficiency PFC without external current sensing. Ensure the application supports the eSIP-16D through-hole package constraints. Verify that the required peak power aligns with the 400 W specification at the target input voltage conditions.

Part Context
