  • Method and apparatus for adjusting the power supply voltage provided to a microprocessor
    Patent number: 5694028
    Abstract: A method and apparatus for adjusting power supplied to a device when the device has a first and a second power input. A first voltage level and a ground potential are provided and a second voltage level is created as a function of the first voltage level. The second voltage level is then buffered with a power transistor and, if the second voltage level is needed for a particular device, the buffered second voltage level is selectively applied to the device. The circuit is disabled when the second voltage supply is not needed.
