Abstract:
A DC-to-DC converter is disclosed. The SMPS driver includes a highside switch having a first terminal, a second terminal and a gate. The first terminal is coupled to an input voltage terminal. The SMPS driver further includes a lowside switch having a first terminal, a second terminal and a gate. The first terminal of the lowside switch is coupled to the second terminal of the highside switch and the second terminal of the lowside switch is coupled to ground. A diode is coupled to the gate of the lowside switch on one side and to a capacitor on the other side. An integrated circuit (IC) is included to generate control signals for switching the highside switch and the lowside switch. The IC includes a highside supply pin, a highside gate control pin, a half bridge pin, a lowside gate control pin and a ground pin. The gate of the lowside switch is coupled to the lowside gate control pin, the highside supply pin is coupled to the diode and the capacitor is coupled to the half bridge pin.
