Abstract
In one aspect, a device includes a first power switch having a first gate, a second power switch paralleled with the first power switch and having a second gate, a gate driver to output a gate drive signal to drive both the first gate and the second gate, a first conduction path to couple the gate drive signal to the first gate, a second conduction path to couple the gate drive signal to the second gate, and a distribution choke to distribute the gate drive signal to the first and second power switches. The distribution choke has a first winding disposed in the first conduction path and a second winding disposed in the second conduction path. The distribution choke is coupled in a differential mode.
