Frequency convertible low voltage driving circuit

The utility model discloses a frequency convertible low voltage driving circuit. A voltage amplitude control circuit disposed on a front end of the driving circuit can provide a variable voltage in a range from 0 to 13V, which can be used as an input voltage of an output alternative frequency control circuit. The output alternative frequency control circuit is a phase reversal circuit, an IN end input adjustable frequency of which is a 0-100KHz square wave. Two output ends of the phase reversal circuit can be used to output the square waves having the same frequency, and the phase difference of the square wave is 180degrees, in addition, amplitudes and input voltage values of the two output square waves are equal to each other. The voltage amplitude control circuit provided in the utility model can be used to supply the alternative frequency control circuit with the 0-13V input voltage, and the output alternative frequency control circuit can be used to provide two output square waves having the adjustable am
