Abstract:
1. A DC-to-DC converter for converting an input voltage to an output voltage, comprising: a comparator configured to compare a first signal having a DC offset determined, at least in part, by a DC reference source with a second signal representative of the output voltage of the DC-to-DC converter and to provide a control signal in response to a comparison of the first and second signals; a driver receiving the control signal from the comparator; a high side switch coupled to the driver, the high side switch receiving the input voltage; and a stability circuit adapted to sense a voltage signal indicative of a load current flowing through the high side switch and generate the second signal based upon the voltage signal and to provide the second signal to the comparator, wherein the driver is adapted to drive the high side switch to control the output voltage of the DC to DC converter.
