Problems solved by technology

[0002] At present, the bitcoin mining machines on the market are basically parallel mining machines using DC / DC (direct current to direct current) chips. Due to the low conversion efficiency of DC / DC, the power supply energy is wasted. At the same time, DC / DC The circuit design of the DC chip is relatively harsh, which increases the design requirements and the cost of production design

Abstract

An embodiment of the invention discloses a serial-connection power supply chip, a serial-connection power supply system, a virtual digital currency mining machine and a server. The serial-connection power supply chip comprises n serial-connection to-be-powered units which are powered in a serial connection manner, a voltage domain is formed in every to-be-powered unit, and voltage of a power source of the serial-connection power supply chip forms n-stage serial-connection voltage domains, wherein n is an integer more than 1; a signal level conversion unit is serially connected between every two adjacent to-be-powered units and used for communication signal level conversion between every two adjacent to-be-powered units. The serial-connection power supply chip has the advantages that the work performance of the to-be-powered units and the whole work performance of the chip are improved, and the whole production cost is reduced.

Description

technical field [0001] The invention relates to power supply technology, in particular to a serial power supply chip and system, a virtual digital currency mining machine, and a server. Background technique [0002] At present, the bitcoin mining machines on the market are basically parallel mining machines using DC / DC (direct current to direct current) chips. Due to the low conversion efficiency of DC / DC, the power supply energy is wasted. At the same time, DC / DC The circuit design of the DC chip is relatively harsh, which increases the design requirements and the cost of production design. [0003] 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 the conversion efficiency of the power supply, the existing technology adopts the serial connection of chips on the printed circuit board (PCB). Power supply mode, that is: the power...
