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
