Adjustable high-resolution power supply output module suitable for SiPM

The invention provides an adjustable high-resolution power supply output module suitable for SiPM, and the module comprises the SiPM, and the power supply output module comprises a PWM unit, an inputvoltage, an energy storage inductor, a switching tube, a diode, a resistance feedback circuit, a low-pass filter, and a software adjustment unit. According to the scheme, the power output module adopts the PWM unit, the energy storage inductor, the switching tube, the diode, the low-pass filter, the resistance feedback circuit and the software adjusting unit; during working, the duty ratio of thePWM pulse is correspondingly adjusted through the voltage value fed back by the resistance feedback circuit, the output voltage value is correspondingly adjusted, and the working voltage of the SiPM is adjusted. Meanwhile, in order to adjust the output voltage more conveniently and flexibly, the voltage value on the resistance feedback circuit is adjusted through the software adjusting unit, and then the working voltage of
