Abstract

A DC power supply, which includes a DC-DC converter and a linear voltage regulator, is disclosed. The DC-DC converter provides a DC power supply signal and a duty-cycle signal, which is based on a duty-cycle of the DC-DC converter. The DC-DC converter provides the DC power supply signal via a power supply output using a setpoint of the DC power supply. The linear voltage regulator provides a DC assist signal to assist the DC-DC converter when an adjusted setpoint of the DC power supply is greater than a voltage of the DC power supply signal. The linear voltage regulator provides the adjusted setpoint using the setpoint and the duty-cycle signal, such that the adjusted setpoint is directly related to the setpoint and to the duty-cycle.
