Abstract
The integrated control circuit is for an electronic circuit, such as a DC-to-DC converter, using current sense information developed across an intrinsic circuit element of the electronic circuit. The integrated control circuit includes a temperature sensor to sense a temperature rise induced by the intrinsic circuit element of the electronic circuit. The temperature error signal and a feedback signal from the intrinsic circuit element of the converter are combined to provide a temperature-corrected feedback signal to a control unit for the converter.
