PFS710EG

Overview

The PFS710EG is a HiperPFS-3 power factor correction controller integrating a continuous conduction mode boost PFC controller, gate driver, and high-voltage power MOSFET in a single eSIP package. It operates within a 90 VAC to 264 VAC input range and supports up to 150 W of output power at 230 VAC. The device features an integrated soft-start, UV/OV protection, brown-in/out detection, and hysteretic thermal shutdown. Switching frequency ranges from 24 kHz to 95 kHz.

Feature Summary

• Integrates CCM boost PFC controller, gate driver, and high-voltage power MOSFET in a low-profile eSIP package
• Eliminates external current sense resistors using innovative control techniques for loss reduction
• Adjusts switching frequency dynamically over load, line voltage, and line cycle to maximize efficiency
• Provides comprehensive protection including soft-start, UV, OV, brown-in/out, and thermal shutdown

Applications

• PC power supplies
• High-power adapters
• Printers
• High-power LED lighting
• LCD TVs

Procurement Notes

Verify the specific suffix (e.g., EG) against the manufacturer's latest datasheet to confirm pinout and packaging details. Confirm availability status as discontinued or limited supply through authorized distributors. Ensure compatibility with EN61000-3-2 Class C/D requirements for your target market.

Selection Notes

Select this component for designs requiring high efficiency across the entire load range without external current sensing resistors. It is suitable for applications needing near unity power factor and minimized EMI filtering due to spread spectrum effects. Consider the eSIP package for compact board space and thermal management needs.

Part Context

The PFS710EG belongs to the HiperPFS-3 family from Power Integrations. This series combines PFC and power switching functions into a single monolithic solution. It is designed to simplify design and reduce component count compared to discrete PFC solutions, offering high reliability and performance for medium-power applications.

Replacement Considerations

Check for direct pin-compatible upgrades within the HiperPFS-4 family if higher power density or improved light-load efficiency is required. Verify that any replacement maintains the same eSIP package dimensions and thermal characteristics.
