Abstract
A variable DC/DC converter system is provided that includes a feedback voltage device and a compensation device. The compensation device and compensation components are integrated into a single integrated circuit. The feedback voltage device is integrated into the single integrated circuit. The values of a first resistor and a second resistor determine the output voltage of the DC/DC converter system. The first resistor and second resistor can be external to the integrated circuit and selectable to provide a desired output voltage. Alternatively, the first resistor can be integrated into the integrated circuit, while the second resistor is external to the integrated circuit and selectable to provide a desired output voltage.
