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 power setting can be adjusted externally by the sense resistor Rs at CS pin. In CV control, multi-mode operations are utilized to achieve high performance and high
● Programmable CV and CC regulation
● Built-in line voltage and primary winding inductance compensation
● Programmable cable drop compensation efficiency. In addition, good load regulation is
● No need for control loop compensation achieved by the built-in cable drop compensation.
