Abstract
The present disclosure pertains to circuits and methods for controlling a boost switching regulator based on inductor current. An input voltage is coupled to a first terminal of an inductor and the second terminal of the inductor is alternately coupled between a reference voltage and a boosted output voltage. The input voltage is further coupled to a first terminal of an integrator circuit, and a second terminal of the integrator circuit may be alternately coupled between the reference voltage and the boosted output voltage, for example, to produce a voltage corresponding to a current in the inductor. The present circuit may be used for voltage control or current control modes, or both, in a boost switching regulator.
