OB2502, OB2502-On High Precision CC/CV Primary-Side Power Switch

OB2502 Description

OB2502x High Precision CC/CV Primary-Side Power Switch GENERAL .
OB2502x is a high performance offline PSR power switch for low power AC/DC charger and adapter applications.

OB2502 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

OB2502 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 shown in the figure below. In CC control, the current and output power setting can be adjusted externall
