Features

Current consumption is reduced with use of the burst mode, promoting standby compatibility with a single converter. The optimized switching device provides ideal partial resonance operation for high efficiency and low noise. The 900V resistant switching device (high-speed IGBT) simplifies design of power supplies for worldwide input. Power consumption under micro-load is extremely low (burst mode). Use of a drain kick circuit eliminates the need for a start-up resistor. The use of a soft drive circuit reduces noise. Incorporates an over-current protection function (primary current detect, Ton.
