Infrared lamp driving circuit of infrared ball machine who steps up

The utility model discloses an infrared lamp driving circuit of infrared ball machine who steps up, including the power, and the energy storage inductance that concatenates with the power in proper order, prevent electric capacity pressure release diode and two infrared lamps, and connect in parallel stack voltage electric capacity between two infrared lamps, and the one end electricity is connected in the energy storage inductance and is prevented between the electric capacity pressure release diode switch transistor of other end electric connection power supply negative pole, and produce the device with the electric PWM ripples of being connected of switch transistor control end. The utility model discloses an automatic stepping up can fall in infrared lamp driving circuit of infrared ball machine who steps up, obtains to be higher than input voltage's voltage to can drive a plurality of infrared lamps of establishing ties that are in, can use the discrete component to put up boost circuit when reducing the components and parts cost, can drive in the past can only the step down drawback of a small number of series connection infrared lamps of drive of infrared lamp driver chip, and its simple structure, be difficult for breaking down.
