    Abstract: A DC-DC converter includes a ramp generator, a threshold voltage circuit, and a control circuit. The ramp generator is configured to generate a voltage ramp. The threshold voltage circuit is configured to generate a threshold voltage. The control circuit is coupled to the ramp generator and the threshold voltage circuit. The control circuit includes a digital pulse width modulator (DPWM) circuit and a loop compensation circuit coupled to the DPWM circuit. The DPWM circuit is configured to generate a power stage switch control signal responsive to a loop compensation value. The loop compensation circuit is coupled to the DPWM circuit. The loop compensation circuit is configured to calculate the loop compensation value responsive to the voltage ramp exceeding the threshold voltage.
