Abstract
A buck converter circuit is disclosed in which one or both of the control switch and the synchronous switch are III-nitride-based depletion mode. An enhancement mode switch is connected with one or both of the III-nitride based switches and operated to prevent conduction of current by the III-nitride based switch until all biases are established for proper operation.
