PFS5276F-TL

Overview

The PFS5276F-TL is a HiperPFS-5 advanced power factor correction controller featuring an integrated 750V PowiGaN switch. It supports peak output powers up to 240W for LLC topologies and 110W for flyback applications. The device operates within a low input voltage range of 90VAC to 305VAC, withstanding surges up to 460VAC. It utilizes quasi-resonant DCM control to reduce switching losses and inductor size. The component is housed in an InSOP-T28F surface-mount package designed for direct PCB thermal conduction without external heat sinks.

• High-power LED lighting systems
• Industrial controls and home appliances

Procurement Notes

Verify availability through authorized distributors as supply status may be restricted. Confirm the specific suffix 'TL' corresponds to the reel packaging configuration required for your assembly process. Ensure compliance with RoHS directives and IEC62368 safety certifications prior to integration into final equipment designs.

Selection Notes

Select this component for designs requiring high power density without external heat sinks. It is suitable for LLC topologies up to 240W or flyback configurations up to 110W. Consider its capability to handle input voltage distortions from generators or UPS sources when designing for robust grid connectivity.

Part Context

This part belongs to the HiperPFS-5 series, which leverages PowiGaN technology for superior performance. It is designed to work alongside chipsets like HiperLCS-2 for LLC converters or InnoSwitch4-CZ for flyback solutions. The series emphasizes compact form factors and reduced component counts compared to traditional silicon-based PFC controllers.
