OB25112, OB25111-On, High Precision CC/CV Primary-Side PWM Power Switch
OB2511x is a high performance offline PSR power switch for low power AC/DC charger and adapter applications.
It operates in primary-side sensing and regulation.
Consequently, opto-coupler and TL431 could be eliminated.
Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated
