Introduction

AI Translation

A Valley Switching Converter (VSC) generally shows lower EMl and higher power conversion efficiency than a conventional hard-switched converter with a fixed switching frequency. The FSQ510 is an integrated Valley Switching Pulse Width Modulation (VS-PWM) 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, undervoltage lockout (UVLO), leading-edge blanking (LEB), optimized gate driver, internal soft-start, temperature compensated precise current sources for loop compensation, and self-protection circuitry. Compared with discrete MOSFET and PWM controller solutions, the FSQ510 can reduce total cost, component count, size and weight; while simultaneously increasing efficiency, productivity, and system reliability. This device provides a platform for cost-effective designs of a valley switching flyback converters.
