AC to DC switching power adaptor circuit
with maximum output power of 90W. Switching power supply is built using
a high voltage power switching regulator IC MC33374 and some other
additional components. The MC33374 IC is a monolithic high voltage power
switching regulators that are specially designed to operate directly
from a rectified AC line source, and in flyback converter applications.
The MC33374 switching power adaptor
combines the required converter functions with a unique programmable
state controller. At various variable AC inputs, it is capable of
serving up to 6 A current at 15V output voltage. This switching power
adaptor is capable of providing an output power in excess of 150W with a
fixed AC input of 100V, 115V, or 230V, and in excess of 90 W with a
variable AC input that ranges from 85V to 265V.
