Abstract
A power supply comprises an output stage configured to provide a supply current, in order to obtain a supply voltage. The power supply also comprises a digital regulator configured to receive a reference voltage information and a measured voltage information and to provide a control signal. The power supply further comprises an inner analog control loop, wherein the inner analog control loop is configured to provide an analog feedback signal, which is based on the supply voltage, to the output stage, to make an analog regulation contribution to a regulation of the supply voltage. A method for supplying power to a load is also disclosed.
