The present invention relates to the technical field of power supply testing, and provides a multi-phase switching power supply efficiency debugging device, method and system. The device includes a control terminal and parameter acquisition equipment; the parameter acquisition equipment collects the working parameters of the multi-phase switching power supply; The multi-phase switching power supply sends working phase adjustment instructions, sequentially controls the multi-phase switching power supply to be in different working phase states, and at the same time sends parameter acquisition instructions to the parameter acquisition device, and draws several efficiency curves according to the received multiple sets of working parameters. The intersection point of the efficiency curve corresponding to the adjacent working phase is determined as the critical point of the adjacent working phase addition and subtraction phase, and the obtained several critical points and the adjacent working corresponding to each of the critical points will be determined. The phase information is stored in the registers of the multi-phase switching power supply to realize the adjustment and configuration of the multi-phase switching power supply. The debugging process takes less time and improves the test efficiency.
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 ...
