Abstract

The embodiment of the invention provides a voltage supply circuit of a pre-driving module of an operation chip, an operation board and a mining machine. The voltage supply circuit comprises a resistor, the first end of which is connected with a power supply; the positive electrode of the diode is connected with the second end of the resistor, and the negative electrode of the diode is connected with reference ground; the voltage supply terminal is connected with the positive electrode of the diode and is adapted to be connected with the first end of the pre-driving module; wherein the second end of the pre-driving module is connected with the reference ground, and the turn-on voltage of the diode is greater than the working voltage of the pre-driving module. Compared with a resistance voltage division mode in the prior art, the power loss is obviously reduced by the implementation mode of the invention.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a voltage supply circuit of a pre-drive module of a computing chip, a computing power board and a mining machine. Background technique [0002] With the rapid development of supercomputers, digital currency mining machines have gradually moved from graphics card mining machines to application specific integrated circuit (ASIC) mining machines with lower power consumption and lower cost. Digital currency miners usually contain multiple computing power boards. In order to improve the computing power, the computing power board is generally a circuit board with a chip array layout. Usually a computing power board is a computing array unit composed of several computing chips (such as ASIC, CPU or GPU). [0003] The core voltage power supply of the computing chips in the computing power board mostly adopts the series power supply mode, in which the positive and negat...
