Design Highlights

　　Accurate primary-side constant voltage/constant current

　　（CV/CC） controller eliminates secondary-side control and

　　optocoupler

　　No current-sense resistors， for maximized effi ciency

　　Low part-count solution for lower cost and higher reliability

　　Over-temperature protection – tight tolerance （±5%） with

　　hysteretic recovery for safe PCB temperatures under all

　　conditions

　　Auto-restart output short circuit and open-loop protection

　　EcoSmart? – Easily meets all existing and proposed international energy effi ciency standards – China （CECP） / CEC / EPA /

　　European Commission

　　ON/OFF control provides constant effi ciency to very light

　　loads

　　No-load consumption 《200 mW at 265 VAC

　　Ultra-low leakage current： 《5 μA at 265 VAC input

　　（no Y capacitor required）

　　Easy compliance to EN55015 and CISPR-22 Class B EMI

　　standards

　　Green package： halogen free and RoHS compliant
