Abstract:
A circuit comprising:an inductor; a high side input switch coupled to a first end of the inductor; a low side input switch coupled to the first end of the inductor; a high side driver coupled to a control node of the high side input switch; a low side driver coupled to a control node of the low side input switch; a high side output switch coupled to a second end of the inductor; a low side output switch coupled to the second end of the inductor; a first bootstrap capacitor coupled between the first end of the inductor and a voltage supply node of the high side driver; a second bootstrap capacitor coupled between the second end of the inductor and a voltage supply node of the low side driver; and a first diode coupled between the voltage supply node of the high side driver and the voltage supply node of the low side driver.
