Abstract
A DC-DC converter includes efficiency reporting circuitry having an output that is a measure of efficiency. In an example, the DC-DC converter has an input voltage, an output voltage, and a switching circuit converting the input voltage to an intermediate voltage, and the efficiency reporting circuitry determines the ratio between the output voltage and the intermediate voltage.
