DC-DC boost circuit and driving circuit board

The utility model provides a DC-DC booster circuit and a driving circuit board, and belongs to the technical field of display. The DC-DC booster circuit comprises a power MOSFET (Metal-Oxide-Semiconductor Field Effect Transistor) and a control module which is electrically connected with a control end of the power MOSFET, the control module is configured to provide a control signal capable of controlling the on and off of the power MOSFET; wherein the voltage value of a high-level signal in the control signals is 0.5-0.8 time of the maximum rated value of the gate source voltage of the power MOSFET. The DC-DC boost circuit can reduce the temperature of the power MOSFET.
