High-side transistor driver having positive feedback for improving speed and power saving

A high-side transistor driver with high-speed high-side transistor driving, comprising:

• a driver circuit, receiving an input signal and generating a driving signal to drive a high-side transistor;
• a first terminal and a second terminal, providing a supply voltage to said driver circuit;
• wherein said second terminal is coupled to a source of said high-side transistor;
• a first diode, coupled between said first terminal and a voltage source;
• a first capacitor, coupled between said first terminal and said second terminal for storing energy for said driver circuit;
• a first transistor, coupled for switching off said high-side transistor in response to said input signal;
• and
• a second capacitor, coupled to said driver circuit for speeding up said driving signal in response to said input signal;
• wherein said driver circuit includes a positive feedback circuit for accelerating said driving signal and for power saving of said driver circuit.
