Compact designs for a printed circuit board (PCB) device of a smartcell battery system are provided. The design includes a number of features, including a direct current to direct current (DCDC) converter having a compact, low-cost design that can provide significant power output despite operating at low voltages. In an example, the DCDC converter includes a number of features, including but not limited to, a closed loop for the primary side winding, integrated leakage inductance, a planar integrated transformer, a modular exchangeable secondary side winding, and two variants of secondary side rectification depending on the desired output voltage. The components of the DCDC converter respectively have planar or substantially planar geometries that enable the DCDC converter to have a compact, planar geometry with an overall thickness of about 1.0 millimeter.
