PFS7539L

Overview

The PFS7539L is a HiperPFS-3 family power factor correction controller designed for continuous conduction mode (CCM) boost applications. It supports peak output powers up to 810W at 230VAC and operates with an input voltage range of 90VAC to 264VAC. The device utilizes an eSIP-16D package, providing high integration and thermal performance. It features fixed-frequency operation up to 123kHz and includes comprehensive protection mechanisms such as output overvoltage, overtemperature, and input undervoltage lockout.

Feature Summary

• Integrates CCM boost PFC controller with advanced digital control for high efficiency
• Features built-in X-capacitor discharge and self-supply startup circuitry
• Includes robust protection against output overvoltage, overtemperature, and short circuits

Applications

• Compact LLC power supplies for electric vehicle chargers
• High-power adapters and USB PD fast charging systems
• Industrial control and home appliance power supplies

Procurement Notes

Verify the specific suffix 'L' indicates the correct package variant against official datasheets. Confirm RoHS compliance status and check for any recent product change notices or end-of-life announcements from Power Integrations prior to finalizing procurement plans.

Selection Notes

Select this component for designs requiring high power density and wide input voltage ranges. Ensure the application topology matches the CCM boost requirement. Verify that the thermal design accommodates the eSIP-16D package dissipation characteristics under maximum load conditions.

Part Context

Part of the HiperPFS-3 series, which offers integrated solutions for power factor correction. This series is designed to simplify design and reduce component count by integrating switches and controllers into compact packages suitable for high-efficiency power supply implementations.

Replacement Considerations

Consult official substitution lists for compatible HiperPFS-3 variants. Verify pin compatibility and electrical specifications before replacing with other models in the same family.
