PFS7526H

Overview

The PFS7526H is a HiperPFS-3 family power factor correction controller integrating a CCM boost PFC controller, gate driver, and 600 V power MOSFET. It supports peak power up to 260 W with an input voltage range of 90 VAC to 264 VAC. The device operates in continuous conduction mode (CCM) and utilizes an eSIP-16D package for through-hole mounting.

Feature Summary

• Integrates a 600 V power MOSFET, gate driver, and CCM boost PFC controller into a single low-profile package.
• Eliminates the need for external current sense resistors by utilizing innovative control techniques that adjust switching frequency based on load and line conditions.
• Features wide bandwidth spread spectrum operation to minimize EMI filtering requirements.
• Includes comprehensive protection mechanisms such as UV, OV, brown-in/out, hysteretic thermal shutdown, cycle-by-cycle current limit, and SOA protection.

Applications

• High-efficiency power supplies for consumer electronics
• Power adapters for IT and telecommunications equipment
• Industrial power supply designs requiring high power factor

Procurement Notes

Verify the specific suffix 'H' indicates the correct package variant (eSIP-16D) and lead-free status. Confirm RoHS compliance details directly from the manufacturer's datasheet. Ensure the ordering part number matches the required pin configuration and thermal characteristics for your PCB layout.

Selection Notes

Select this component for designs requiring integrated PFC and MOSFET functionality without external current sensing resistors. It is suitable for applications needing high efficiency across varying loads and reduced EMI filter size. Consider the eSIP-16D package constraints for thermal management and board space.

Part Context

The PFS7526H belongs to the HiperPFS-3 series from Power Integrations. This family combines PFC control and power switching in a single IC to simplify design and improve reliability. It targets medium-power applications where high power factor and efficiency are critical regulatory and performance requirements.

Replacement Considerations

Check for direct pin-compatible substitutes within the HiperPFS-3 or HiperPFS-4 families. Verify if higher or lower power variants (e.g., PFS7523H, PFS7524H) meet the specific wattage and voltage requirements of the target application.
