Abstract

A power supply system uses a DC-DC power converter () for supplying an output load. A compensation circuit () is connected between the input to the DC-DC converter and the output of the DC-DC converter and it provides a compensating path in response to a voltage drop at the output of the DC-DC converter caused by a surge in the output load. The power supply system further comprises a low drop out regulator () as the output load, which low drop out regulator () having an input connected to the DC-DC power converter and the compensation circuit, and an output connected to an output terminal (C) for connection to a further output load. This enables the DC-DC power converter to have a low current capability, because a large current demand can be met by the DC supply to the DC-DC converter.
