1. A charge pump circuit, comprising a phase clock generation module, an acceleration response control module and a plurality of sub charge pump modules, wherein an output end of the phase clock generation module is connected to a clock control end of each of the sub charge pump modules, the plurality of sub charge pump modules are connected in parallel and then correspondingly connected to an input power supply end and an output voltage end, the output voltage end is connected to an input end of the acceleration response control module, and an output end of the acceleration response control module is connected to input ends of the phase clock generation module and each of the sub charge pump modules;
the phase clock generation module generates a plurality of clock signals with a fixed phase difference, to correspondingly control the plurality of sub charge pump modules to generate output voltages, and meanwhile after the output voltages are measured by means of the acceleration response control module, separately outputs a logic signal to the phase clock generation module and each of the sub charge pump modules, so that when the output voltages do not reach a target value, the phase clock generation module generates an acceleration clock signal to generate the output voltages rapidly, and when the output voltages reach the target value, the phase clock generation module controls each of the sub charge pump modules to maintain the normal output voltage.
