Abstract
A DC-DC converter includes an output power stage and a driver circuit. The output stage switches an input voltage to a switch node using a first transistor in response to a top-gate signal received at a top-gate node, and the switch node to ground using a second transistor in response to a bottom-gate signal received at a bottom-gate node. The driver circuit that provides the top- and bottom-gate signals in response to high- and low-side switch signals, respectively, activates the top-gate signal by actively regulating the top-gate node to a first voltage between a threshold voltage and a breakdown voltage of the first transistor using charge from the bottom-gate node, and activates the bottom-gate signal by actively regulating a second voltage provided to the bottom-gate node between a threshold voltage and a breakdown voltage of the second transistor using charge from the top-gate node.
