ABSTRACT:
A gate drive supply circuit generating a high-level supply voltage and a low-level supply voltage for driving N-type high-side and low-side power MOSFETs in a multiple-output, low-voltage DC-DC converter integrated circuit. The gate drive supply circuit includes a boost regulator for generating the low-level supply voltage and a charge pump doubler for generating the high-level supply voltage. Both the high-level supply voltage and the low-level supply voltage are distributed to one or more regulators, including but not limited to buck or boost type regulators.
