WS3413中文资料稳先微电子数据手册PDF规格书

General Description

The WS3413 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 WS3413 integrates 500V power MOSFET, using DIP-8 package, producing up to 260mA output current. It can achieve excellent constant current performance with very few external components.
