Abstract

An AC-DC voltage conversion integrate circuit that integrates all the control and protection circuits, as well as the power transistors, into a single module. Passive components, such as the transformer and capacitors, are very small, as the switching frequency is in the KHz or MHz range. Including one or more integrated switched mode power supply ICs in every wall outlet allows for providing a plurality of DC voltages from such outlets.
