Abstract
A boost converter with a flying capacitor topology is provided. The flying capacitor is charged during a first half of a cycle. During a second half of the cycle, the output voltage of the boost converter is supplied from Vdd until the output voltage approximately reaches Vdd. At that point, the flying capacitor is used to provide the output voltage.
