PFS5178F-TL

Overview

The PFS5178F-TL is a HiperPFS-5 advanced power factor correction (PFC) controller IC from Power Integrations. It integrates a 750V PowiGaN switch to achieve high efficiency and power density in PFC applications. The device supports peak output powers up to 240W for LLC topologies when paired with HiperLCS-2 chips. It operates within an input voltage range of 90VAC to 305VAC, maintaining high power factor across the load range. Key electrical characteristics include an efficiency of up to 98.3% from 10% to 100% load and no-load power consumption under 40mW at 230VAC.

Feature Summary

• Integrates a 750V PowiGaN switch for low switching loss and zero-loss current sensing
• Enables compact system design by reducing component count and inductor size without requiring heat sinks
• Features digital input voltage peak detection for reliable performance under distorted grid conditions

Applications

• LLC topology power supplies up to 240W
• Personal computers and printers
• High-power adapters and USB PD 3.1 fast chargers
• Industrial control systems

Procurement Notes

Verify the specific suffix 'TL' indicates tape and reel packaging configuration. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure compatibility with InSOP-T28F package thermal management requirements on the PCB substrate.

Selection Notes

Select this component for designs requiring high power density and efficiency in the 240W PFC stage. It is suitable for pairing with HiperLCS-2 controllers in LLC topologies. Consider its capability to handle input voltages up to 305VAC and transient surges up to 460VAC for robust grid adaptability.

Part Context

This part belongs to the HiperPFS-5 series, which utilizes advanced PowiGaN technology. It succeeds previous generations like HyperPFS-3 by offering higher integration and improved thermal performance via the InSOP-T28F package. The series targets universal input voltage applications with stringent efficiency standards.

Replacement Considerations

Direct substitutes within the same family include PFS5175F-TL, PFS5176F-TL, and PFS5174F-TL. These variants offer different power ratings while sharing the same control architecture and package type.
