FSQ510MX Description
A Valley Switching Converter ( VSC) generally s hows lower EMI and higher power conversion efficiency than a conventional hard-switched converter with a fixed switching frequency. The FSQ510 is an i ntegrated Valley Switching Pulse Width Modulation (VS-PWM) controller and SenseFET specifically designed for offline Switch-Mode Power Supplies (SMPS) for valley switching with m inimal ex ternal c omponents. T he VSPWM...
