An embodiment of the invention relates to a power control device configured to provide current-sharing control in a power converter including a plurality of power trains. The power control device transmits or receives a synchronization signal on a synchronization node to initiate a time frame that includes a plurality of time slots, and to control a switching activity of a power switch in a respective power train. The power control device further includes a current sharing bus node on which a digital current-sharing signal is transmitted in a designated time slot. The power control device determines a load current of the power converter and controls a power train current employing current data received on the current-sharing bus node from another power control device. The power control device may be a master power control device that transmits the synchronization signal on the synchronization node.
