| description | The invention discloses a PCB layout structure of a DC-DC power module. An inductor, a lower MOSFET and an output capacitor are placed in a first PCB surface, and an upper MOSFET and an input capacitor are placed on a second PCB surface. The upper MOSFET is adjacent to the input capacitor in position. The drain electrode of the lower MOSFET and the source electrode of the upper MOSFET are symmetrically stacked and are connected through a via hole. The lower MOSFET and the upper MOSFET are connected with the upper end of the inductor, and large area of copper is laid on the connecting portion. The input capacitor is adjacent to the rear end of the inductor, and the lower MOSFET is adjacent to the front end of the inductor. The output capacitor is adjacent to the rear end of the inductor and connected with the rear end of the inductor through a copper plane. The PCB layout structure of the DC-DC power module has the advantages that the area of two large current circuits of a DC-DC power circuit is decreased, th |
