Overview

WS3411 Product Description WS3411 Active PFC Non-isolated Buck LED Driver Features � High Power Factor Correction, Low Total Harmonic Distortion � Dynamic Temperature Compensation � 500V Power MOSFET Integrated � No Auxiliary Winding For Supplying � SOP8 Package, Up To 260mA Output Current � Valley Switching, High efficiency, Low EMI � Automatic Compensate the Inductance Variation � Automatic Adapt to the Change of Output Voltage � LED Short Circuit Protection � Over Voltage Protection � Over Temperature Protection � Open Circuit Protection � Few External Components Applications � LED Driver Supply General Description The WS3411 is designed for active PFC non-isolated buck LED driver.
It operates at valley switching mode with high efficiency, low EMI and High PF.
The output current automatically adapt to the variation of the inductance and the output voltage.
The truly constant current LED is realized.
The WS3411 integrates 500V power MOSFET, using SOP8 package, producing up to 260mA output current.
It can achieve excellent constant current performance with very few external components.
The WS3411 offers rich protection functions, including over voltage protection, LED short circuit protection, cycle by cycle current limiting, dynamic temperature compensation, over temperature protection and soft start.
WS3411 consumes very low start current and operation current, driving LED efficiently under universal AC input(85VAC~265VAC).
WS3411 is available in SOP8 package.
