OB2550, OB2550-On, High Precision CC/CV Primary-Side Controller
OB2550 is a high performance offline PSR controller 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 as
