Datasheet Summary
Green Mode Power Switch for Valley Switching Converter
- Low EMI and High Efficiency
FSQ0365, FSQ0265, FSQ0165, FSQ321
Description 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 operation with minimal external ponents. The PWM controller includes an integrated fixed- frequency oscillator, under- voltage lockout, Leading- Edge Blanking (LEB), optimized gate driver, internal soft- start, temperature- pensated precise current sources for...
