Abstract: This work described a new power supply topology that benefits portable device and low power electronics. At the other end of the spectrum, it is also applicable to higher bus voltage systems like solar panels and electric vehicles that must split higher voltages into usable domains. The new topology, which we named waterfall regulator, is describe herein and named as such for its salient features reminiscent of a waterfall. It opens up a new realm of possibilities for supra low power, low voltage and low current systems. The mode of operation consists of splitting a raw supply source into smaller voltage domains which can then be used for powering individual element of a system or powering multiple independent units. We describe here the first report of successful energy recycling version of this novel system. The devices are composed of a series of low dropout voltage regulators and current spillways circuits (pass MOSFET). The regulators share current passing thought their respective load and supplement current through a current spillway as required. Control is achieved through a cascade architecture and can be scaled up to higher order devices.
