PFS7628L

Overview

The PFS7628L is a HiperPFS-4 device integrating a continuous conduction mode (CCM) boost power factor correction controller, gate driver, and 600 V power MOSFET. It eliminates external current sense resistors to reduce power loss. The component operates with a switching frequency of 60 kHz and supports an input voltage range of 90 VAC. It features a maximum output power capability of 110 W and includes integrated protection mechanisms such as UV, OV, brown-in/out, and hysteretic thermal shutdown.

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 control techniques
• Adjusts switching frequency over output load, input line voltage, and input line cycle
• Features wide bandwidth spread spectrum effect to minimize EMI filtering requirements

Applications

• Power factor correction stages in AC/DC converters
• High-efficiency offline power supplies
• Consumer electronics requiring low no-load power consumption

Procurement Notes

Verify the specific suffix 'L' against official Power Integrations documentation, as standard listings often utilize 'C' or 'TL' suffixes for this family. Confirm package type and moisture sensitivity level prior to ordering. Ensure design compatibility with the HiperPFS-4 family specifications regarding thermal management and PCB layout requirements.

Selection Notes

Select this component for applications requiring high efficiency across the entire load range, particularly at light loads. The integrated MOSFET and controller simplify design by removing external sense resistors. Consider the 600 V rating and 110 W power capability when matching system requirements. Verify availability of the specific 'L' variant through authorized distributors.
