FSQ321 Green Mode Fairchild Power Switch

A Valley Switching Converter generally shows lower EMI and higher power conversion efficiency than a conventional hard-switched converter with a fixed switching frequency. The FSQ-series is an integrated Pulse-Width Modulation (PWM) controller and SenseFET specifically designed for valley switching .

FSQ321 Features

* Optimized for Valley Switching Converter (VSC)

* Low EMI through Variable Frequency Control and Inherent Frequency Modulation

* High Efficiency through Minimum Voltage Switching

* Narrow Frequency Variation Range Over Wide Load and Input Voltage Variation

* Advanced Burst-Mode
