Digitally controlled regulator i.e. digitally controlled buck-boost converter, has digital pulse width modulator for generating switching signals based on mapped value and feeds generated switching signals into switching circuit

摘要

The regulator i.e. digitally controlled Buck-boost converter (100), has a direct current (DC)-DC H-bridge driver switching circuit (102) for receiving an input voltage signal and generating an output voltage signal. A controller (108) generates a pulse width modulation (PWM) control value based on a value of the output signal. A quantizer/mapper (112) receives the PWM control value and generates a mapped PWM control value. A digital pulse width modulator (DPWM) (118) generates switching signals based on the mapped PWM value and feeds the generated switching signals into the switching circuit. An independent claim is also included for a method for controlling a digitally controlled regulator.
