Power supply and method of supplying power to a load using an internal analog control loop

摘要

A power supply has an output stage configured to provide a supply current to obtain a supply voltage. The power supply also includes a digital controller configured to receive reference voltage information and measured voltage information and to provide a control signal. The power supply further includes an inner analog control loop, wherein the inner analog control loop is configured to provide an analog feedback signal based on the supply voltage to the output stage to provide an analog regulation contribution to a regulation of the supply voltage. A method of supplying power to a load is also disclosed.
