OB2539中文资料High Precision CC/CV PSR PWM Controller/Power Switch数据手册OB规格书

描述 Description

OB2535 is a high performance offline PWM Power switch for low power AC/DC charger and adapter applications. It can achieve ＼5% precision constant voltage (CV) and high precision constant current (CC). It operates in primary-side sensing and regulation. Consequently, opto-coupler and TL431 could be eliminated.
