Abstract
A digitally controlled buck boost regulator includes an H-bridge circuit including a plurality of switches configured to receive an input voltage signal and generate an output voltage signal based on the input voltage signal and switching signals provided thereto. A controller generates a pulse width modulation (PWM) control value in response to a value of the output voltage signal, and a quantizer/mapper receives the PWM control value and provides a first mapping to a mapped PWM control value if the PWM control value is outside a predetermined range of PWM control values, and generates a second mapping to a mapped PWM control value if the PWM control value is within the predetermined range. A digital pulse width modulator is configured to generate switching signals based on the mapped PWM control value, and provide the generated switching signals to the H-bridge circuit.
