CM6301
CM6301 is Quasi-Resonant smps controller manufactured by Champion.
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.
APPLICATIONS
TV/Monitor SMPS AC-DC Adapters/Chargers
