PFS5277F-TL

Overview

The PFS5277F-TL is a HiperPFS-5 series power factor correction controller featuring an integrated 750V PowiGaN switch. It supports peak output powers up to 240W for LLC topologies and operates within a wide input voltage range of 90VAC to 305VAC, withstanding surges up to 460VAC. The device utilizes InSOP-T28D surface-mount packaging for efficient thermal dissipation directly to the PCB substrate without requiring external heat sinks.

Feature Summary

• Integrates a 750V PowiGaN switch to minimize switching losses and eliminate the need for external current sensing components.
• Employs digital input voltage peak detection to maintain reliable performance despite waveform distortion from UPS or generator sources.
• Features internal X-capacitor automatic discharge and high-voltage self-biasing during startup to reduce component count.
• Includes a digitally enhanced power factor circuit that compensates for distortion caused by EMI filters and rectifier bridges.

Applications

• High-power adapters and USB PD 3.1 fast charging systems
• Industrial control equipment and home appliances
• Personal computers, printers, and LCD televisions
• Video game consoles
• High-power LED lighting fixtures

Procurement Notes

Verify the specific suffix against official Power Integrations documentation to confirm exact ordering parameters. Confirm availability status through authorized distributors as supply conditions may vary. Ensure compliance with RoHS directives and relevant IEC62368 safety certifications prior to integration into final designs.

Selection Notes

Select this component for designs requiring high efficiency across the entire load range without additional thermal management hardware. It is suitable for applications demanding robust input voltage tolerance and active surge control. Consider its compatibility with LLC topologies for higher power outputs or flyback configurations for lower power requirements.

Part Context

This part belongs to the HiperPFS-5 family, which advances power factor correction technology using silicon carbide-based PowiGaN switches. The series focuses on reducing system size and component count while maintaining high power factors under varying line conditions and loads.

Replacement Considerations

The PFS5176F-TL serves as a verified alternative within the same HiperPFS-5 series for comparable power factor correction applications.
