Abstract
A DC-DC converter comprises a capacitor arrangement and a switching arrangement for controlling coupling of the capacitor arrangement to a converter input during a loading phase and to a converter output during a storing phase. The converter cycles between charge pumping stages and charge holding phases, giving rise to a converter switching frequency. A variable output load is controlled thereby to maintain a constant converter switching frequency.
