A converter utilizes a low voltage battery to develop a higher potential by the use of capacitors which are charged sequentially according to digital waveforms provided by counting type circuits and gates. The charge transfer circuits afford a low impedance charging path and a high impedance discharge path via a series of transmission gate controlled capacitors.

The apparatus permits the conversion of low battery voltages while being completely compatible with ultra-miniature electronic systems.
