OB2305 High Precision CC/CV Primary-Side Controller GENERAL DESCRIPTION FEATURES OB2305 is a high performance offline PSR  Primary-side sensing and regulation without controller for low power AC/DC charger and TL431 and opto-coupler adapter applications. It operates in primary-side  High precision constant voltage and current sensing and regulation. Consequently, regulation at universal AC input opto-coupler and TL431 could be eliminated.  Multi-mode PWM/PFM operation for efficiency Proprietary Constant Voltage (CV) and Constant improving Current (CC) control is integrated as shown in the  Less than 30mW standby power consumption figure below.
