1. A system, comprising:
a first comparator having a first positive input, a first negative input, a first control input, and a first output;
a second comparator having a second positive input, a second negative input, a second control input, and a second output;
a pulse-width modulation (PWM) controller coupled to the first and second outputs and the first and second control inputs and having a control output;
a ramp generator having a first ramp output coupled to the first positive input and a second ramp output coupled to the second negative input;
an analog-to-digital converter (ADC) having an ADC output;
an adder having a positive input, a negative input coupled to the ADC output, and an adder output; and
a voltage controller having an input coupled to the adder output and an output coupled to the ramp generator.
