Abstract: An electrical device includes an integrated circuit having device circuitry and a boost converter coupled to the device circuitry. The boost converter includes a digital integrator circuit having: a first comparator; a second comparator; a counter configured to count up, count down, and pause based on a first output signal provided by the first comparator and based on a second output signal provided by the second comparator; and a digital-to-analog converter (DAC) configured to provide a feedback adjustment signal for the boost converter based on a count value provided by the counter.
