Abstract:
A switching converter circuit for switching one end of an inductor therein between plural voltages according to a pulse width modulation (PWM) signal to convert an input voltage to an output voltage. The switching converter circuit has a driver circuit including a high side driver, a low side driver, a high side sensor circuit, and a low side sensor circuit. The high side sensor circuit is configured to sense a gate-source voltage of a high side metal oxide semiconductor field effect transistor (MOSFET), to generate a low side enable signal for enabling the low side driver to switch a low side MOSFET according to the PWM signal. The low side sensor circuit is configured to sense a gate-source voltage of a low side MOSFET, to generate a high side enable signal for enabling the high side driver to switch a high side MOSFET according to the PWM signal.
