Claim 0:
1. A system comprising:
a voltage converter circuit comprising:
an inductor comprising a first inductor end and a second inductor end;
a first switch coupled between a voltage source and the first inductor end and comprising a first gate terminal; and
a second switch coupled between the first inductor end and ground and comprising a second gate terminal; and

a ripple voltage detector circuit, comprising:
a pulse generator coupled to the first gate terminal of the first switch and the second gate terminal of the second switch;
and
a first control loop coupled to the pulse generator and configured to:
determine an output ripple voltage in an output voltage of the voltage converter circuit based on a measurement of the output voltage;
determine a ripple coefficient based on the output ripple voltage;
determine a reference inductor current based on the ripple coefficient; and
control a peak value of the inductor current based on the reference inductor current during a discontinuous conduction mode (DCM).
