OB25133 Datasheet | On-Bright

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...
