It incorporates a primary control and drive circuit with an avalanche-rated power MOSFET. Covering the power range from below 17 watts for a 230 VAC input, or to 13 watts for a universal (85 to 264 VAC) input, this device can be used in a wide range of applications, from DVD players and VCR player/recorders to ac adapters f...
