Abstract
A switched-mode power supply circuit includes a first controller for controlling power to a main power output through a first transformer, and a second controller for controlling power to a control output through a second transformer. In order to effect a very low power stand-by mode, the second controller turns off the first controller, the second controller only operating. When a load is selectively coupled across the control output, the second controller detects this load and turns on the first controller thereby effecting the operating mode.
