OB2502PCP, OB2502-On, High Precision CC/CV Primary-Side Power Switch
OB2502x 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
OB2502PCP Features
* Primary-side sensing and regulation without TL431 and opto-coupler
* High precision constant voltage and current regulation at universal AC input
* Multi-mode PWM/PFM operation for efficiency improving
* Integrated 2A/3A MOSFET
* Good dynamic response with synchronous rectifier
