Abstract:
A voltage regulator includes a converter and a modulator. The converter includes a switching circuit coupled to an inductor for converting an input voltage to an output voltage. The modulator controls the switching circuit in a buck mode of operation, a boost mode of operation, and an intermediate buck-boost mode of operation. During the buck-boost mode of operation, the modulator controls the switching circuit during each switching cycle to sequentially switch between three different switching states, including a first switching state that applies the input voltage across the inductor, a second switching state that applies a difference between the input and output voltages across the inductor, and a third switching state that applies the output voltage across the inductor. The modulator is controlled based on voltage applied across or current flowing through the inductor to regulate the output voltage to a target level.

Claim (Index 7):
The voltage regulator of  claim 1 , further comprising:\n an error amplifier circuit that develops a modulation control voltage based on comparing a voltage indicative of said output voltage with an output reference indicative of a target level of said output voltage; wherein said switching circuit further comprises:\n a buck power stage that selectively couples a first end of said inductor either to said input voltage or to a reference source voltage as controlled by a buck pulse control signal; and \n a boost power stage that selectively couples a second end of said inductor either to said output voltage or to said reference source voltage as controlled by a boost pulse control signal; and \n wherein said modulator uses said input voltage, said output voltage and said modulation control voltage to generate said buck pulse control signal and said boost pulse control signal.
