ABSTRACT:
A buck-boost switching regulator which includes a first switch, a first diode, an inductor, a second switch, a second diode, and a controller for controlling the first switch and the second switch, the controller being configured to receive a current signal indicative of a inductor current flowing in the inductor, and generating a signal indicative of an average current flowing in the inductor, the average current being utilized to control the first switch and the second switch, wherein the controller includes a first compensator circuit for outputting a voltage error signal, a second compensator circuit for outputting a current error signal and a modulator circuit to output a first control signal to control the first switch and a second control switch to control the second switch.
