A modulator for use with a voltage regulator includes an input for receiving an input voltage, an output for providing a periodic triangular wave form and at least one input for receiving an indication that the voltage regulator is in a discontinuous current mode of operation. The circuitry within the modulator generates the periodic triangular wave form responsive to the input voltage and the indication that the voltage regulator is in the discontinuous current mode of operation. The circuitry further continuously increases a period of the periodic triangular wave form responsive to a decreased load in a discontinuous current mode of operation of the voltage regulator.
