PFS5175F-TL

Overview

The PFS5175F-TL is a Power Factor Correction (PFC) controller from the HiperPFS-5 family, manufactured by Power Integrations. It integrates a 750 V PowiGaN switch to deliver high efficiency across the load range. The device supports peak output power up to 240 W for LLC topologies and operates within an input voltage range of low line to 305 VAC. It features variable-frequency DCM control, digital input voltage peak detection, and an integrated X-capacitor discharge circuit. The component is housed in an InSOP-T28F package with a back-side source for effective PCB heat dissipation.

Feature Summary

• Integrates a 750 V PowiGaN switch to minimize conduction losses and enhance efficiency.
• Employs variable-frequency discontinuous-conduction-mode (DCM) control to reduce switching losses and allow smaller inductor sizes.
• Includes digital power factor enhancement circuits to compensate for distortion caused by EMI filters and rectifier bridges.
• Features a back-side source in the InSOP-T28F package for direct thermal conduction to the PCB substrate.

Applications

• Personal computers and printers
• LCD televisions and video game consoles
• High-power adapters and USB PD 3.1 fast chargers
• High-power LED lighting systems

Procurement Notes

Verify the specific ordering suffix 'TL' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the InSOP-T28F package dimensions align with the target PCB footprint and thermal management design. Ensure compliance with RoHS directives and IEC62368 safety standards for the intended end-use application environment.

Selection Notes

Select this component for designs requiring high power factor correction in applications up to 240 W. It is suitable for LLC topologies when paired with HiperLCS-2 chips. Consider its variable-frequency DCM control for reduced magnetic component size. Evaluate the integrated PowiGaN technology for superior efficiency compared to traditional silicon-based solutions in similar power classes.

Part Context

The PFS5175F-TL belongs to the HiperPFS-5 series, which utilizes advanced PowiGaN technology for power factor correction. This family is designed to provide high efficiency and compact form factors without requiring external heat sinks. The series supports various topologies, including LLC and flyback configurations depending on the specific model variant and power requirements.

Replacement Considerations

The PFS5176F-TL is a related member of the HiperPFS-5 family offering higher power capabilities. Verify compatibility with existing reference designs and control loops when substituting or upgrading within the series.
