OB2530P, OB2530P-On, High Precision CC/CV Primary-Side Power Switch

OB2530P High Precision CC/CV Primary-Side Power Switch GENERAL .
OB2530P is a high performance offline PSR power switch for low power AC/DC charger and adapter applications.

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 620V MOSFET
* Good dynamic response
* Programmable CV an

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
