The invention relates to the technical field of power-supply testing, and provides a device, method and system for regulating the efficiency of a multi-phase switching power supply. The device comprises a control terminal and parameter acquisition equipment. The parameter acquisition equipment acquires working parameters of the multi-phase switching power supply. The control terminal continuouslysends a work phase adjusting instruction to the multi-phase switching power supply and sequentially controls the multi-phase switching power supply to be in a state with different work phases, meanwhile, a parameter acquisition instruction is sent to the parameter acquisition equipment, multiple efficiency curve graphs are drawn according to multiple groups of received working parameters, intersections of the efficiency curves corresponding to the adjacent work phases are determined as critical points of adjacent work phase adding and subtracting phases, the determined critical points and information of the adjacent work phases corresponding to the critical points are stored in a register of the multi-phase switching power supply, the multi-phase switching power supply is adjusted and configured, time consumed by the regulating process is short, and the testing efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of power supply testing, and in particular relates to a multi-phase switching power supply efficiency debugging device, method and system. Background technique [0002] With the development trend of ultra-large-scale integrated circuits, the power density of chips is getting higher and higher, and the increase in power consumption requires board-level power supplies to provide greater current output. For a DC step-down switching power supply greater than 25A, the efficiency of the single-phase switching power supply and the difficulty in heat dissipation will restrict its performance. The multi-phase power supply can reduce the current of MOSFETs and inductors by multiples, and can reduce the hot spots on the printed circuit board or devices. In addition, the multi-phase power supply also has the characteristics of low ripple voltage and small required inductor volume. [0003] In order for the multi-phase ...
