1. An electrically-actuated turbocharger assembly including an electronics assembly, comprising:
a printed circuit board (PCB), having a first side and a second side, included in a PCB housing coupled to a turbocharger housing;
a plurality of electrical components mounted on the first side of the PCB;
a heat sink, configured to receive cooling fluid from a source within a vehicle, positioned between the turbocharger housing and the PCB housing and adjacent to-the second side of the PCB; and
a cooling fluid conduit, configured to communicate the cooling fluid from a fluid inlet to a fluid outlet, wherein the cooling fluid conduit is positioned adjacent to the first side of the PCB and directly contacts an outer surface of the electrical components.
