Classification: CPC H  G | IPC G  H

Claim 10:
11. A ripple voltage detector circuit, comprising:
a pulse generator configured to generate a signal to control a direct current-to-direct current (DC-DC) converter; and
a control loop coupled to the pulse generator, wherein the control loop is configured to:
obtain a measurement of an output voltage of the DC-DC converter;
determine an output ripple voltage of the output voltage based on the measurement;
determine a ripple coefficient based on the output ripple voltage;
determine a reference inductor current based on the ripple coefficient;
determine a peak value of an inductor current of the DC-DC converter during a switching cycle; and
transition a switching state of the DC-DC converter based on the reference inductor current and the peak value of the inductor current.
