OB2513x
High Precision CC/CV Primary-Side PWM Power Switch
GENERAL DESCRIPTION
Features
OB2513x is a high performance offline PSR power
- Primary-side sensing and regulation without switch for low power AC/DC charger and adapter
TL431 and opto-coupler applications. It operates in primary-side sensing
- High precision constant voltage and current and regulation. Consequently, opto-coupler and TL431 could be eliminated. Proprietary Constant regulation at universal AC input
- Multi-mode PWM/PFM operation for efficiency
Voltage (CV) and Constant Current (CC) control is integrated as shown in the figure below. improving
- Good dynamic response
In CC control, the current and output...
