Description A Quasi-Resonant Converter (QRC) typically shows lower EMI and higher power conversion efficiency com- pared to conventional hard-switched converter with a fixed switching frequency. Therefore, a QRC is well suited for noise-sensitive applications, such as color TV and audio. Each product in the FSCQ-Series contains an integrated Pulse Width Modulation (PWM) controller and a SenseFET, and is specifically designed for quasi- resonant off-line Switch Mode Power Supplies (SMPS) with minimal external components. The PWM controller includes an integrated fixed frequency oscillator, under volt- age lockout, leading edge blanking (LEB), optimized gate driver, internal soft start, temperature-compensated pre- cise current sources for a loop compensation, and self protection circuitry. Compared with a discrete MOSFET and PWM controller solution, the FSCQ-Series can reduce total cost, component count, size, and weight, while simultaneously increasing efficiency, productivity, and sys- tem reliability. These devices provide a basic platform that is well suited for cost-effective designs of quasi-resonant switching flyback converters.
