Abstract:
A buck regulator for converting an input DC voltage, V, into an output DC voltage level includes a coupled inductor for outputting the DC voltage level, and an error amplifier for sensing an error in the outputted DC voltage level and a pulse width modulator (PWM) providing a pulse waveform having a duty cycle responsive to the error. Also, included are a V voltage driver for outputting the V voltage level responsive to the pulse waveform, and a super voltage driver for outputting a super voltage level, Vss, responsive to the pulsed waveform, wherein the super voltage level is higher than the V voltage level. The outputted super voltage level is complementary to the outputted V voltage level. Also included are dual MOSFETs, which have gates for, respectively, receiving the super voltage level and the V voltage level. The dual MOSFETs drive the coupled inductor for outputting the DC voltage level.
