Abstract:
A buck/boost regulator controller is provided. The buck-boost regulator controller controls four switches in an H-bridge configuration to control voltage regulation. The buck/boost regulator controller includes a digital error amplifier and buck-boost control logic. The digital error amplifier provides a multi-bit digital error voltage signal that is based on the difference between the output voltage and the desired output voltage. The buck-boost control logic controls the opening and closing of the four switches in the H-bridge based, in part, on the multi-bit digital error voltage signal.
