Overview

WS3410 Product Description WS3410 Active PFC Non-isolated Buck LED Driver Features � High Power Factor Correction, Low Total Harmonic Distortion � Dynamic Temperature Compensation � No Auxiliary Winding For Supplying � 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 WS3410 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 WS3410 using SOT23-6 package,It can achieve excellent constant current performance with very few external components.
The WS3410 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.
WS3410 consumes very low start current and operation current, driving LED efficiently under universal AC input(85VAC~265VAC).
WS3410 is available in SOT23-6 package.
