Claim:
1. A DC-to-DC converter, comprising: a first switch coupled to an input voltage node and an inductor, wherein the first switch if on, is configured to increase current that flows through the inductor; a second switch coupled to the inductor and an output voltage node, wherein the second switch if on, is configured to decrease the current that flows through the inductor; and a driver coupled to the first and second switches and configured to alternately turn on and off the first and second switches, wherein the driver includes two transistors connected in series, wherein the amount of time to turn off the first switch is based on a value of a conductive resistance from each of the two transistors, and a voltage drop between gate and source terminals of the first switch; wherein, while the first switch is off, the driver is to provide a voltage level to an adaptive voltage node, the voltage level being inversely proportional to the current that flows through the inductor so as to decrease a variation of the amount of time to turn off the first switch wherein the first switch is a power metal oxide field effect transistor (MOSFET).
