Patent ID: 7859875

Claim:
A universal power adapter for converting an input voltage to one of a plurality of selectable preset output voltages, comprising: an input for receiving an input voltage from a power source; an output for supplying an output voltage selected from a plurality of different preset output voltages, the output including a plurality of terminals; a voltage converter circuit for converting the input voltage to the plurality of preset output voltages, wherein the voltage converter circuit includes a plurality of floating voltage divider legs and each of the terminals of the output is connected to a respective floating voltage divider leg; and a connector tip connectable to the output for connection of a power consuming device to the output through the connector tip, wherein the connector tip includes a plurality of pins, each pin engaging a respective terminal when the connector tip is connected to the output, and connection of the connector tip to the output connects at least one of the floating voltage divider legs to a ground in the voltage converter circuit and, thereby, connects one of the plurality of preset output voltages to the connector tip.
