Abstract
A low-power-consumption high-speed zero-current switch includes a delay controller, a driving stage and a power transistor MN, wherein: an input of the delay controller is connected with an external clock CLK, an output of the delay controller is connected with an input of the driving stage, and an output of the driving stage is connected with a gate of the power transistor MN; the delay controller includes a gate signal generator, a sampling circuit and a current controller, and three of which form a negative feedback loop for stabilizing the turn-on voltage Vand the turn-off voltage Vto 0, so that when the power transistor MN is turned on or off, the source-drain voltage thereof is 0. The present invention no longer uses a high-power-consumption high-speed comparator, but uses a low-power-consumption delay controller to generate turn-on and turn-off signals of the power transistor.
