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 DIP8 package, producing up to 260mA output current. It can achieve excellent constant current performance with very few external components. The WS3413 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. WS3413 consumes very low start current and operation current, driving LED efficiently under universal AC input(85VAC~265VAC). WS3413 is available in DIP8 package.
