Description
technical field [0001] The invention relates to the field of mainboard power supply, in particular to a multi-phase high-current power supply module. Background technique [0002] As users have more and more requirements for server functions, the number of functional units on the server motherboard gradually increases. However, limited by the structural size and processing process of the motherboard, it is impossible to increase the size of the PCB infinitely. Therefore, as the server motherboard has more functions, the density of components on the motherboard is getting higher and higher without increasing the PCB area. In this way, higher requirements will be put forward for the design of the motherboard. [0003] Power supply unit - as the basis for maintaining the work of the motherboard, it is also limited by the density of components, especially in places where the supply current demand is large, it is necessary to leave enough space on the PCB layout to lay a wide c...
