- Part of the OB2512RN-On comparator family.
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.
- Programmable CV and CC regulation
