Claim:
1. A method for controlling a DC-to-DC converter including at least a first regulated operating mode and an unregulated operating mode different from the first regulated operating mode, comprising: repeatedly switching a control switching device of the DC-to-DC converter between its conductive and non-conductive states to regulate a magnitude of an output voltage of the DC-to-DC converter according to a magnitude of a reference voltage, in the first regulated operating mode of the DC-to-DC converter; in response to a command to enter the unregulated operating mode, changing from the first regulated operating mode to the unregulated operating mode; in the unregulated operating mode, simultaneously: comparing the magnitude of the reference voltage to a target value; and in response to the magnitude of the reference voltage being within a predetermined proximity to the target value, operating in a slew operating mode including:
