Abstract
A voltage elevation circuit supplying additional voltage for gate switching having an elevated power supply connected to a first node of a capacitor using a transistor. The elevated power supply and booting circuit providing additional voltage for gate switching applications. One application is a MOSFET output driver application having a 3 Volt power supply. One configuration using a switch to charge a capacitor using a first voltage supply and then providing additional voltage by a boot device and by switching in an elevated power supply to maintain an elevated voltage at the node.
