Description: OB2500P High Precision CC/CV Primary-Sid e Power Switch GENERAL DESCRIPTION OB2 500P is a high performance offline PSR power switch for low power AC/DC charge r and adapter applications. It operates in primary-side sensing and regulation . Consequently, opto-coupler and TL431 could be eliminated. Proprietary Consta nt Voltage (CV) and Constant Current (C C) control is integrated as shown in th e figure below. In CC control, the curr ent and output power setting can be adj usted externally by the sense resistor Rs at CS pin. In CV control, multi-mode operations are utilized to achieve hig h performance and high efficiency. In a ddition, good load regulation is achiev ed by the built-in cable drop compen
