A voltage converter includes a switch having a switching loss that decreases as a switching frequency of the switch decreases. The voltage converter further includes a controller programmed to vary the switching frequency based on a duty cycle of the switch and a current input to the switch to reduce switching losses or reduce a ripple current magnitude.
