FSQ510MX Datasheet

Switching Converters, Regulators & Controllers


A Valley Switching Converter (VSC) generally shows lower EMI and higher power conversion efficiency than a conventional hard-switched converter with a fixed switching frequency. The FSQ510MX (H or M) is an integrated valley switching pulse width modulation (VSPWM) controller and SenseFET specifically designed for offline switch-mode power supplies (SMPS) for valley switching with minimal external components. The VS-PWM controller includes an integrated oscillator,under-voltage lockout (UVLO), leading-edge blanking (LEB), optimized gate driver, internal soft-start,temperature-compensated precise current sources for loop compensation, and self-protection circuitry. FSQ510MX Features • Uses an LDMOS Integrated Power Switch• Optimized for Valley Switching Converter (VSC)• Low EMI through Variable Frequency Control and Inherent Frequency Modulation• High Efficiency through Minimum Drain Voltage Switching• Extended Valley Switching for Wide Load Ranges• Small Frequency Variation for Wide Load Ranges• Advanced Burst-Mode Operation for Low Standby Power Consumption• Pulse-by-Pulse Current Limit
