Overview

WS3442 ProductDescription Features  Critical Conduction Mode Operation  Internal 500V Power MOSFET  No Auxiliary Winding  Ultra Low Operating Current  ±3% LED Output Current Accuracy  Efficiency up to 93%  LED Open Protection  LED Short Protection  Current Sensing Resistor Short Protection  Thermal Regulation Function  Available in SOP-8 Package and DIP-7 Package Applications  LED Candle Light  LED Bulb, Spot Light  T8/T10 LED String  Other LED Lighting Typical Application(SOP-8 Package) Non-isolated Buck Offline LED Driver Description The WS3442 is a high precision buck constant current LED driver.
The device operates in critical conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting.
The WS3442 integrates a 500V power MOSFET.
The operating current of the IC is very low.
So it doesn’t need the auxiliary winding for supplying the chip.
It can achieve excellent constant current performance with very few exte...
