PFS714EG

Overview

The PFS714EG is a HiperPFS-4 power factor correction controller integrating a continuous conduction mode boost PFC controller, gate driver, and 600 V power MOSFET in a single low-profile package. It eliminates external current sense resistors to reduce power loss. The device features wide bandwidth spread spectrum for EMI reduction, advanced digital line monitoring, and analog core control for low no-load consumption. It includes an integrated non-linear error amplifier, programmable Power Good signal, selectable power limit, and comprehensive protection against UV, OV, brown-in/out, thermal shutdown, and short circuits.

Feature Summary

• Integrates CCM boost PFC controller, gate driver, and 600 V power MOSFET in a single package
• Eliminates external current sense resistors using innovative frequency adjustment control technique
• Features wide bandwidth spread spectrum effect to minimize EMI filtering requirements
• Includes programmable Power Good signal and user-selectable power limit functionality

Applications

• Power factor correction stages in AC/DC power supplies
• High-efficiency offline converter front-ends
• Applications requiring minimized EMI filtering components

Procurement Notes

Verify the specific suffix 'EG' against the manufacturer's official datasheet to confirm pinout, thermal characteristics, and packaging details. Ensure the component matches the required voltage ratings and protection features for your design. Cross-reference with authorized distributors to confirm availability and authenticity, as supply status may vary.

Selection Notes

Select this component when designing high-efficiency PFC stages that require integration of the power MOSFET and controller. It is suitable for applications needing reduced BOM count by eliminating current sense resistors. Consider its spread spectrum capabilities if EMI compliance is critical. Verify compatibility with your target output power and input line voltage ranges.

Part Context

The PFS714EG belongs to the HiperPFS-4 family from Power Integrations. This series combines digital and analog techniques to optimize performance across the entire load range. It is designed for mid-to-high power applications where efficiency and size are priorities, offering a compact solution compared to discrete PFC designs.

Replacement Considerations

Check for direct substitutes within the HiperPFS-4 family or previous generations like HiperPFS-3. Ensure any replacement maintains the same voltage rating, package type, and protection features. Verify pin compatibility if a direct swap is intended.
