OB2512RN
High Precision CC/CV Primary-Side Power Switch
GENERAL DESCRIPTION
FEATURES
OB2512RN is a high performance offline PSR Primary-side sensing and regulation without
power switch 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 Good dynamic response
figure below.
