Document Type and Number:
WIPO Patent Application WO/2024/032465
Kind Code:
A1
Abstract:
A load-current-tracking-based mode switching circuit and method for a voltage converter. The circuit comprises a mode control unit and an adjustment unit, wherein the mode control unit is used for generating a mode control signal, and controlling, on the basis of the mode control signal, a voltage converter to switch between a step-up mode and a step-down mode; and the adjustment unit is connected to the mode control unit, and is used for acquiring an output signal of an error comparator in the voltage converter, and generating a feedback current, so as to adjust the flip-flop level of the mode control signal, which is in the mode control unit. The concept of the present invention is ingenious, and the method is rational and effective, such that various different load environments of a voltage converter are taken into full consideration, and the stability of output voltages in different environments is fully ensured.
