PFS5173F-TL

Overview

The PFS5173F-TL is a HiperPFS-5 series power factor correction controller featuring an integrated 750V PowiGaN switch. It operates in continuous conduction mode (CCM) with a switching frequency range of 22kHz to 123kHz. The device supports input voltages from 90VAC to 264VAC and delivers up to 165W output power. It utilizes an InSOP-T28F package for efficient thermal management.

Feature Summary

• Integrates a 750V PowiGaN switch for high efficiency and reduced component count
• Provides digital input voltage peak detection for reliable performance under distorted supply conditions
• Features internal X-capacitor discharge and self-supply startup functionality
• Supports quasi-resonant DCM control to minimize switching losses and inductor size

Applications

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

Procurement Notes

Verify the specific suffix 'TL' indicates tape-and-reel packaging when ordering. Confirm the device belongs to the HiperPFS-5 family, which differs functionally from the HiperPFS-4 series. Ensure compatibility with the intended PCB layout for the InSOP-T28F package before finalizing procurement.

Selection Notes

Select this component for designs requiring high power density without external heat sinks. It is suitable for applications needing robust performance under UPS or generator-powered voltage distortions. Consider its integration level if minimizing bill-of-materials complexity is a priority over discrete component flexibility.

Part Context

This part belongs to the HiperPFS-5 family, succeeding earlier generations like HiperPFS-4. It represents Power Integrations' advanced approach to PFC by combining control logic with high-voltage GaN technology. This integration allows for significant reduction in passive component size compared to traditional silicon-based solutions.

Replacement Considerations

The PFS5275F-TL is listed as a similar alternative within the same product family. Verify functional equivalence regarding pinout and control characteristics before substitution.
