PFS5273F-TL

Overview

The PFS5273F-TL is an advanced power factor correction (PFC) controller IC from the HiperPFS-5 series, manufactured by Power Integrations. It integrates a 750V PowiGaN switch to achieve high efficiency and power density in offline applications. The device supports peak output powers up to 185W and operates with a maximum voltage rating of 750V. Designed for surface-mount installation, it utilizes an InSOP-T28F package to facilitate direct thermal conduction 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.
• Features an InSOP-T28F package with a back-side source for efficient thermal dissipation directly into the PCB.
• Includes internal X-capacitor discharge and high-voltage self-supply functionality during startup.

Applications

• Personal computers and printers
• LCD televisions and video game consoles
• High-power adapters and USB PD fast chargers
• Industrial control systems and home appliances

Procurement Notes

Verify the specific suffix 'TL' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with the InSOP-T28F footprint and thermal design requirements. Cross-reference the RoHS compliance status and moisture sensitivity level prior to procurement to meet assembly standards.

Selection Notes

Select this component for designs requiring high power factor correction in compact form factors. The integrated PowiGaN technology allows for reduced passive component counts and smaller inductor sizes compared to traditional solutions. Consider the thermal management capabilities of the InSOP-T28F package when evaluating system-level heat dissipation strategies.

Part Context

This part belongs to the HiperPFS-5 family of advanced PFC controllers. The series is characterized by high integration levels and innovative control methods that reduce overall system size. It is designed to operate reliably across a wide input voltage range, including conditions where input voltages may surge significantly above nominal levels.

Replacement Considerations
