Abstract
A voltage regulating module includes a fine regulating charge pump and a voltage-multiplying charge pump. The first output voltage of the fine regulating charge pump is V1=m*V0, a second output voltage of the voltage-multiplying charge pump is V2=n*V0, and a total output voltage of the voltage regulating module V=V1+V2. V0 is an input voltage, a value of m ranges from 0 to 1, and n is an integer greater than or equal to 1.
Claims16
A voltage regulating module, comprising:
- a fine regulating charge pump and a voltage-multiplying charge pump connected to each other, wherein a first output voltage of the fine regulating charge pump is V1=m*V0, a second output voltage of the voltage-multiplying charge pump is V2=n*V0, and a total output voltage of the voltage regulating module is V=V1+V2, wherein V0 is an input voltage, a value of m ranges from 0 to 1, and n is an integer greater than or equal to 1;
- and
- wherein the voltage regulating module further comprises a comparator, two input ends of the comparator are respectively connected to a preset voltage and the total output voltage, the total output voltage is controlled by a plurality of switches, and in a case where the total output voltage is not greater than the preset voltage, the comparator outputs a control signal to improve a working frequency of the plurality of switches.
