Independent output control for single-inductor, bipolar outputs, buck-boost converters
Abstract:
Methods and apparatuses drive a Single Inductor Bipolar Output Buck-Boost configured to provide both positive output voltage and a negative output voltage. The power stage is driven so that an amount of energy to be accumulated during a charging phase is controlled via the duty cycle of a first control signal, and an amount of energy to be discharged during an independent discharging phase in a buck-type or boost-type is controlled via the duty cycle of a second control signal.
