Overview
The PFS5176F-TL is a HiperPFS-5 family power factor correction controller featuring an integrated 750 V PowiGaN switch. It supports peak output powers up to 240 W and operates within a universal input voltage range of 85 VAC to 305 VAC. The device utilizes variable-frequency discontinuous-conduction-mode control to minimize conduction losses and reduce inductor size. It includes digital input voltage peak detection and power factor enhancement circuits to maintain high efficiency across the load range.
Feature Summary
- Integrates a 750 V PowiGaN switch for low switching loss and zero-loss current sensing
- Employs variable-frequency DCM control to reduce component count and inductor size
- Features digital power factor enhancement to compensate for EMI filter distortion
- Includes internal X-capacitor discharge and self-biasing startup functionality
Applications
- Personal computers and printers
- LCD televisions and video game consoles
- High-power adapters and USB PD 3.1 fast chargers
- Industrial controls and home appliances
Procurement Notes
Verify the specific suffix TL indicates reel packaging when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing designs.
Selection Notes
Select this component for designs requiring high efficiency at light loads without external heat sinks. It is suitable for LLC topologies up to 240 W when paired with HiperLCS-2 controllers. Ensure the application benefits from the reduced bill of materials and compact InSOP-T28F package footprint.
Part Context
This part belongs to the HiperPFS-5 series, which introduces PowiGaN technology to power factor correction applications. The series aims to replace traditional discrete PFC solutions by integrating the switch and controller into a single highly efficient package.
Replacement Considerations
The PFS5174F-TL serves as a lower power variant within the same family. Verify that the target application power requirements align with the specific model's capabilities before substituting.
