Abstract: A wiring device including a first printed circuit board (PCB) that includes a first direct current (DC) output port and a second DC output port. The wiring device further includes a second PCB electrically connected with the first PCB, the second PCB including a planar transformer integrated with a surface of the second PCB and configured to output power at one or more DC voltage levels, a switch connected to the planar transformer, and a microcontroller. The microcontroller includes an electronic processor and is configured to control delivery of power from the planar transformer to at least one of the first DC output port and the second DC output port using the switch. The switch may have a Gallium Nitride (GaN) chemistry or a Silicon Carbide (SiC) chemistry.
