Abstract
A DC-DC boost converter includes an inductor coupled between an input voltage and an input node, a diode coupled between the input node and an output node, and an output capacitor coupled between the output node and ground such that an output voltage is formed across the output capacitor. A switch selectively couples the input node to ground in response to a drive signal. Control loop circuitry includes an error amplifier to generate an analog error voltage based upon a comparison of a feedback voltage to a reference voltage, the feedback voltage being indicative of the output voltage, a quantizer to quantize the analog error voltage to produce a digital error signal, and a drive voltage generation circuit to generate the drive signal as having a duty cycle based upon the digital error signal.
