One embodiment provides A DC-DC converter system that includes a high side switch and a low side switch coupled to a power supply, each switch is configured to transition from an on state to an off state and from an off state to an on state to deliver current to an inductor and a load. This embodiment also includes low side driver circuitry configured to control the conduction state of the low side switch and configured to drive the low side switch with a first gate driving signal during a first mode of operation and with a second gate driving signal during a second mode of operation. The first gate driving voltage is stronger than the second gate driving signal and the second gate driving signal is configured to cause a slower switch transition of the low side switch compared to the first gate drive control signal.
