CR6237 - High Precision CC/CV Primary-Side PWM Power Switch

CR623X is a high performance offline PWM power switch for low power AC/DC charger and adaptor applications. It operates in primary-side sensing and provides constant voltage (CV) and constant current (CC) regulation without TL431 and opto-coupler. A typical output CC/CV curve is shown as in the Fig..
