OB2531 High Precision CC/CV Primary-Side PWM Controller Product Specification GENERAL DESCRIPTION FEATURES OB2531 is a high performance offline PWM „ 5% Constant Voltage Regulation at Universal controller for low power AC/DC charger and AC input adaptor applications. It operates in primary-side „ High Precision Constant Current Regulation at 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 externally by the sense resistor Rs at CS pin. In CV control, multi-mode operations are utilized to achieve high performance and high efficiency.
