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.
