PFS7537H

Overview

The PFS7537H is a Power Factor Correction (PFC) controller from the HiperPFS-3 family, designed for continuous conduction mode (CCM) applications. It operates within a switching frequency range of 22kHz to 123kHz and supports an input voltage range of 90VAC to 265VAC. The device delivers a peak power capability of 610W with a maximum output voltage of 385VDC. It features a supply voltage range of 10.2V to 15V and functions reliably across a temperature range of -40°C to 150°C. The component is housed in a 16-SSIP package with 13 leads and a bare pad, designated as eSIP-16D.

Feature Summary

• Integrates high-voltage startup circuitry and soft-start functionality for simplified design
• Provides cycle-by-cycle current limiting and overvoltage protection mechanisms
• Utilizes a proprietary quasi-resonant-like control technique for enhanced efficiency

Applications

• High-power LED lighting drivers
• Computer and server power supplies
• Telecommunications equipment power systems

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's latest datasheet to confirm pinout and thermal characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for any product change notices or end-of-life announcements prior to finalizing procurement plans.

Selection Notes

Select this component for designs requiring high power density and wide input voltage ranges. Ensure the thermal management solution accommodates the eSIP-16D package constraints. Verify that the target application falls within the specified 610W peak power limit and CCM operational requirements.

Part Context

This part belongs to the HiperPFS-3 family, which combines PFC and flyback controllers in some variants, though the PFS7537H specifically focuses on CCM PFC control. It is manufactured by Power Integrations, a leader in efficient power conversion solutions. The series is known for integrating multiple functions into a single IC to reduce component count.

Replacement Considerations

Consult official substitution lists for verified alternatives. Generic cross-references may not match the specific eSIP-16D footprint or internal control logic.
