AC to DC 90W Switching Adaptor Power

AC to DC adapter circuit switching contactors maximum output power of 90W. Switching power supply is constructed using a high voltage power switching regulator IC MC33374 and additional components. The MC33374 is a monolithic IC for high-voltage power switching regulators that are specially designed to operate directly from a rectified AC line source, and the flyback converter applications.

The MC33374 switching adapter power converter combines the functions of the programmable controller requires a unique state. Several AC variable inputs, is capable of serving up to 6 A of current to an output voltage of 15V. This switching power adapter is capable of providing an output exceeding 150 W with a fixed AC input of 100V, 115V, or 230V, and more than 90 W with a variable AC input ranging from 85V to 265V.
