1. A driving output circuit, wherein the driving output circuit is used to drive an input signal and generate an output signal, wherein the driving output circuit comprises:
a timer for outputting a timing signal based on a duration of a high level of the input signal;
a bootstrap module for generating a first turn-on voltage based on the input signal;
a charge pump, connected to the timer, for generating a second turn-on voltage based on the timing signal;
a driving module, connected to the bootstrap module and the charge pump, respectively;
wherein, the driving module comprises an upper driving metal-oxide-semiconductor field-effect transistor (MOSFET) and a lower driving MOSFET connected to the upper driving MOSFET, and wherein the upper driving MOSFET and the lower driving MOSFET are connected at a signal output; the first turn-on voltage and the second turn-on voltage are used to make the upper driving MOSFET and the lower driving MOSFET be turned on respectively so as to cause the signal output to output the output signal.
