Description: OB2513x High Precision CC/CV Primary-Sid e PWM Power Switch GENERAL DESCRIPTION OB2513x is a high performance offline PSR power switch for low power AC/DC ch arger and adapter applications. It oper ates in primary-side sensing and regula tion. Consequently, opto-coupler and TL 431 could be eliminated. Proprietary Co nstant Voltage (CV) and Constant Curren t (CC) control is integrated as shown i n the figure below. In CC control, the current and output power setting can be adjusted externally by the sense resis tor Rs at CS pin. In CV control, multi- mode operations are utilized to achieve high performance and high efficiency. In addition, good load regulation is ac hieved by the built-in cable drop co
