Abstract
A power converter may be configured to power multiple output loads, including a main output load and at least one auxiliary output load. The power converter may include control circuitry that controls power delivery to output circuits coupled to the output loads. When the main output load is operating in a reduced power mode, the control circuitry may trigger the switching circuitry to increase the supply of power in order to increase the auxiliary voltages used to power the auxiliary loads if one or more of the auxiliary voltages drops below a threshold due to the main output load operating in the reduced power mode.
