Abstract
In a voltage regulator including an inductor current flowing through a sense element with a first temperature coefficient, and a current sense circuit for generating a current sense signal related to the first temperature coefficient by sensing the inductor current from the sense element, a temperature compensation device and method determines a second temperature coefficient according to the first temperature coefficient and temperature variation, and produces a compensation signal with the second temperature coefficient to compensate variations in the current sense signal caused by the first temperature coefficient.
