Abstract: The invention relates to the control of auxiliary power supply connected in parallel with a switch of a switching regulator. A switch and a diode are included within the connection to the auxiliary supply. The auxiliary supply switch enables a flow of current to the auxiliary supply when the auxiliary supply switch is on and the switch in parallel is off. The auxiliary diode prevents a reverse flow of current when the switch in parallel is on. The auxiliary power supply is suitable to supply of current in both stages of switching regulator operation, to configurations with a common node carrying either type of potential, steady or switching, provides supply of current at high efficiency in the switching stage of switching regulator operation, and provides high efficiency over a wide range of operating conditions of the switching regulator.
