Switching Circuit

摘要

A switching circuit includes a driver circuit DRV2 that outputs voltage for turning on and off a first transistor switch M2, positioned at a low potential side with respect to a load, among a plurality of transistor switches disposed in series between an input voltage and a ground; and a control circuit that causes the driver circuit DRV2 to output a first voltage that turns the first transistor switch M2 on upon an output voltage of the driver circuit DRV2 rising while the first transistor switch M2 is off and to cause the driver circuit DRV2 to suspend output of the first voltage upon the output voltage of the driver circuit DRV2 dropping after the driver circuit DRV2 outputs the first voltage.

1. A switching circuit comprising:
a driver circuit configured to output voltage for turning on and off a first transistor switch, positioned at a low potential side with respect to a load, among a plurality of transistor switches disposed in series between an input voltage and a ground; a control circuit configured to cause the driver circuit to output a first voltage that turns the first transistor switch on upon an output voltage of the driver circuit rising while the first transistor switch is off and to cause the driver circuit to suspend output of the first voltage upon the output voltage of the driver circuit dropping after the driver circuit outputs the first voltage; and an up/down counter and a variable delay circuit, wherein an output of the up/down counter is coupled to an input of the variable delay circuit, and an output of the variable delay circuit is coupled to an input of the driver circuit.
