Description: On-Bright confidential to OB2560 High P recision CC/CV Primary-Side Controller GENERAL DESCRIPTION OB2560 is a high p erformance offline PSR controller for l ow power AC/DC charger and adapter appl ications. It operates in primary-side s ensing and regulation. Consequently, op to-coupler and TL431 could be eliminate d. Proprietary Constant Voltage (CV) an d Constant Current (CC) control is inte grated as shown in the figure below. In CC control, the current and output pow er setting can be adjusted externally b y the sense resistor Rs at CS pin. In C V control, multi-mode operations are ut ilized to achieve high performance and high efficiency. In addition, good load regulation is achieved by the built
