ABSTRACT:
A buck boost switching regulator includes a buck switch and a boost switch controlled by a first and second comparator, respectively. The first comparator generates a duty cycle control signal for the buck switch in response to the difference between the regulator output voltage and a control voltage corresponding to a desired regulator output voltage. The second comparator generates a duty cycle control signal for the boost switch in response to a supply voltage.
