Abstract
A power converter includes a high side device, a low side device connected to the high side device at a switch node, an inductor connected to the high side device and the low side device at the switch node, and a high side driver. The high side driver is configured to drive a gate of the high side device at a first current for a first period of time. In response to the first period of time ending, the high side driver is configured to step down the first current for a second period of time. In response to the second period of time ending, the high side driver is configured to drive the gate of the high side device at the first current.
