An embodiment of the present invention provides a series power supply circuit, which is characterized in that it includes: a first power supply unit connected in parallel to provide a first power supply voltage; a second power supply unit, the second power supply unit The units are connected in series to provide a second power supply voltage; the power supply unit provides a power supply voltage for the first power supply unit and the second power supply unit; the unit to be powered has a first power supply unit access terminal Accepting the power supply voltage provided by the first power supply unit. The power conversion efficiency is significantly better than the current industry's traditional parallel and series power supply architectures. At the same time, the overall power supply current of the circuit is reduced, the power supply circuit is further simplified, and the material cost of the device is saved.
Description
technical field [0001] The invention relates to power supply technology for integrated circuit chips, in particular to a series power supply circuit, system and method. Background technique [0002] With the continuous and rapid development of cloud computing and server-level large-scale computing, as well as the global awareness of environmental protection and energy conservation, energy efficiency has become a very important indicator in the hardware computing system. [0003] At present, computing equipment based on large-scale integrated circuits adopts the traditional parallel power supply architecture, which has obvious disadvantages such as excessive current and low energy efficiency, and increases the requirements for chip circuit design and the cost of production design. With the development of semiconductor technology, the working power supply voltage of the chip is getting lower and lower, and the working current is getting bigger and bigger. In order to maximize ...
