The invention provides an output voltage regulating circuit of a power supply and a control method of the output voltage regulating circuit of the power supply. The output voltage regulating circuit of the power supply comprises a comparison module, a first control module and a switch module, wherein the switch module comprises at least two switches; the comparison module is used for generating feedback signals according to output voltage and reference voltage of the power supply; the first control module is connected with the comparison module and the switch module and used for controlling switching on or switching off of the switches in the switch module according to the feedback signals so as to regulate the output voltage of the power supply. With the adoption of the technical scheme, the output voltage regulating circuit of one power supply can be equivalent to the output voltage regulating circuit of different power supplies, the structure is simple, and the stability of the output voltage regulating circuit of the power supply is improved.
Description
technical field [0001] The invention relates to the technical field of power supplies, in particular to an output voltage regulating circuit of a power supply and a control method thereof. Background technique [0002] With the development of electronic technology and the continuous improvement of people's living standards, the use of various electronic products is becoming more and more popular. Electronic products need a stable working voltage when they are working. In order to meet the working voltage of electronic products, a stable output voltage adjustment circuit of the power supply is usually set on the printed circuit board (Printed Circuit Board; PCB) to adjust the output of the power supply according to the actual situation. Voltage, so that the power supply can output a stable voltage, so that electronic products can work normally. [0003] The output voltage regulation circuit of the power supply in the prior art generally includes a boost (Boost) regulation ci...
