This circuit converts an input voltage that can range from above （6 V) and below （4 V） the desired output voltage (5 V). Normally, such a circuit must provide both step-up and step-down actions. However, if the input ground can be floated, as is often the case with a battery, an inverter can be used instead of a transformer or a complicated and lossy step-up/down circuit by fixing the most-negative output voltage at ground.
