CM6301 Quasi-Resonant smps controller DESCRIPTION Quasi-resonantzero-voltageswitching (ZVS) topology. Ripple reduction during light to moderate load while minimizing the range of operating frequency. Ultra-low start up current and operating current. Soft Start Green-Mode operation The CM6301 is a current-mode primary controller specifically tailored for offline Quasi-resonant ZVS fly-back converters. Load detect function minimizes the range of operating frequency during light to moderate load while reducing output ripple.
