PFS5274F-TL

Overview

The PFS5274F-TL is a Power Factor Correction (PFC) controller from the HiperPFS-5 series, manufactured by Power Integrations. It integrates a 750V PowiGaN switch to enable high efficiency and power density in compact designs. The device supports peak output powers up to 240W for LLC topologies and up to 110W for flyback topologies. It operates with universal input voltages ranging from low line to 305VAC, maintaining high power factor across the load range.

Feature Summary

• Integrates a 750V PowiGaN switch to minimize switching losses and eliminate external current sensing components.
• Features an InSOP-T28F package with a back-side source for direct thermal conduction to the PCB, removing the need for heat sinks.
• Includes digital input voltage peak detection to ensure reliable performance under distorted voltage conditions such as UPS or generator supply.
• Provides internal X-capacitor discharge and self-biasing startup functionality to reduce component count.

Applications

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

Procurement Notes

Verify the specific suffix 'TL' against the manufacturer's official datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure compatibility with the intended PCB layout for the InSOP-T28F package, particularly regarding thermal pad connection requirements. Cross-reference the part number with authorized distributors to confirm current availability status and lead times.

Selection Notes

Select this component for designs requiring high power density without active cooling solutions. It is suitable for applications utilizing LLC resonant converters up to 240W or flyback converters up to 110W. Consider its integration of the PowiGaN switch if minimizing bill-of-materials complexity and improving efficiency at light loads are primary design goals.

Part Context

This part belongs to the HiperPFS-5 family, which utilizes advanced PowiGaN technology to achieve superior performance compared to previous generations like HiperPFS-3. The series focuses on reducing system size through high-frequency operation and integrated thermal management capabilities inherent to the InSOP packaging.

Replacement Considerations

Direct replacements within the same family include PFS5275F-TL and PFS5276F-TL. These variants offer similar pinouts and functionalities but may differ in maximum power handling capabilities or specific threshold settings. Verify electrical parameters before substitution.
