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.
