Abstract:
1. A power conversion system comprising: a switching converter including: an analog-to-digital converter (ADC) for sampling a voltage from the output voltage port of the switching converter, wherein the ADC has a non-uniform response characteristic comprising a regulation bin within which a change in the sampled voltage from the output port of the switching converter will produce no change in a digital output of the ADC; an error circuit configured to output an error signal comprising a difference between a reference signal and the digital output of the ADC; a compensator filter for filtering the error signal and producing a pulse width modulator (PWM) control signal; and a PWM module configured to receive the PWM control signal and to output a PWM waveform for alternately driving the at least one switch of the switching converter between an off state and an on state, and further wherein the PWM module is adapted to:
