A power-up control circuit controls the initial application of power to a system having multiple loads and multiple voltage supply levels. The control circuit causes the power to each load to rise equally, and limits the voltage levels to all loads to the lowest voltage being controlled by the control circuit. As each load reaches its target voltage, its voltage no longer limits the control circuit. The voltages to the remaining loads continue to rise, and loads whose target voltages are reached continue to drop out of the control circuit, until each load is receiving its target voltage.
