原边控制六级能效恒压/恒流系列产品

SP2689AFC is a high performance offline PSR power switch for low power AC/DC charger and adapter applications. Using 3D packaging technology, integrated 7A/650V MOSFET in the SOP8 package.It operates in primary-side sensing and regulation. Thus, opto-coupler and TL431 are not required. In CC control • Less than 75mW standby power consumption at 230VAC with typical application circuit\n• Less than ±5% constant voltage and current regulation at universal AC input\n• Adjustable constant current and output power setting\n• Eliminates all control loop compensation circuitry\n• Built-in Leading E;
