Abstract
An efficient power supply architecture includes a bus converter and a voltage regulation module, which are arranged on the same side of an XPU substrate, that is, on the side opposite to the XPU. By shortening a power transmission path between the voltage regulation module and the XPU and a power transmission path between the bus converter and the voltage regulation module, the loss along the transmission paths is reduced. On the other hand, by integrating passive components with the bus converter, or by arranging the voltage regulation module and the bus converter on an intermediate substrate, the assembly process of the system is simplified.
Claims20
An efficient power supply architecture, comprising:
- an XPU,
- an XPU substrate, the XPU being arranged on a top surface of the XPU substrate;
- a smart card motherboard, a bottom surface of the XPU substrate being attached to, fixed to, and electrically connected with a top surface of the smart card motherboard;
- a voltage regulation module, arranged in vertical correspondence with the XPU and electrically connected to the XPU;
- and
- a bus converter, electrically connected to the voltage regulation module,
- wherein the bus converter and the voltage regulation module are arranged below the XPU.
