Abstract:
The present invention discloses a synchronous driver circuit, comprising: an inductor having one end coupled to an input voltage; a first power transistor having one end coupled to the other end of the inductor and another end supplying an output voltage; a second power transistor having one end coupled to the other end of the inductor and another end coupled to ground; a control circuit for controlling the operation of the first and second power transistors; a gate driver coupled to the control circuit and having an output controlling the gate of the first power transistor; and a bootstrap capacitor having one end coupled to a voltage node and the other end coupled to the other end of the inductor, the voltage across the bootstrap capacitor being provided as the operational voltage of the gate driver.
