Description
A Quasi -Resonant Converter (QRC) typically shows lower EMI and higher power conversion efficiency compared to a conventional hard -switched converter with a fixed switching frequency. Therefore, a QRC is well suited for noise -sensitive applications, such as color T V and audio. Each product in the FSCQ series contains an integrated Pulse Width Modulation (PWM) controller and a SenseFET . This series is specifically designed for quasi-resonant off-line Switch Mode Power Supplies (SMPS) with minimal external components. The PWM controller includes an integrated fi xed frequency oscillator, under -voltage lockout, leading - edge blanking (LEB), optimized gate driver, internal soft- start, temperature-compensated precise current sources for 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 increasing efficiency, productivity, and system reliability. These devices provide a basic platform for cost -effective designs of quasi-resonant switching flyback converters.
