The power consumption of a switch-mode power converter can be determined based upon at least one of a converter drive signal pulse width or a converter drive signal frequency. In one embodiment, a land grid array cartridge structure includes: a deformable thin film having at least one aperture configured to hold a substantially liquid metal, whereby in a compressed state of the deformable thin film, the substantially liquid metal of the deformable thin film is configured to electro-mechanically couple a carrier and a socket base. Additionally, the lower surface of the board is equipped with a pair of laterally mounted rockers that extend downward from this surface. Consequently, a voltage applied to the switching element can be suppressed, and furthermore, the winding ratio of the transformer does not need to be increased.
