1. A boost system for driving a high side n-channel MOSFET, comprising:

  • a boost converter configured to supply a boost voltage to a gate of an n-channel MOSFET;

    a boost converter power supply for providing a first current to the boost converter to power the boost converter;

    a second boost converter power supply for providing a second current to the boost converter, the second current being larger than the first current, the second boost converter power supply operating for a selected period of time to start the boost converter until the output of the boost converter reaches a selected voltage level.
