Beschreibung
Zusammenfassung:	The invention relates to a BOOST circuit with an adjustable output voltage software. The BOOST circuit comprises a main control chip, a power supply circuit and a power supply circuit, wherein the main control chip is used for outputting a first PWM (Pulse-Width Modulation) signal according to a set voltage value during initial starting and controlling a switching tube to be alternately switched on and switched off; the BOOST power supply module is used for storing and releasing energy in a reciprocating manner; the output voltage feedback module is used for dividing the output voltage of the BOOST power supply module to obtain feedback voltage; the overvoltage protection module is used for outputting a low level when the feedback voltage is larger than an upper threshold value or outputting a high level when the feedback voltage is smaller than a lower threshold value and acting on the switching tube through a second diode; and the main control chip is also used for outputting a second PWM signal with a fixe
