Abstract
A pulse-width modulation control circuit includes a first transistor and a signal generator. The first transistor includes a first terminal coupled to a power source and a second terminal coupled to a first input of a controlled component. The signal generator includes a first node coupled to a gate of the first transistor. The signal generator is configured to receive a comparison value and a comparison criterion and to compare the comparison value to a counter value based on the comparison criterion. In response to the comparison value satisfying the comparison criterion with respect to the counter value, the signal generator is configured to send a control signal to the gate of the first transistor to generate a pulse edge of a pulse of a pulse-width modulated signal.
