Abstract
It is an object of one or more embodiments of the present disclosure to provide a single-inductor dual-output (SIDO), or single-inductor multiple-output (SIMO), Buck switching converter which can supply opposite polarity current to its outputs, through an inductor. It is a further object of one or more embodiments, when one output has an overshoot and the other output is below a reference, to enable discharging the overshoot output to the other output, resulting in a significant charge recycling and considerable increase in power efficiency. Still further, it is an object of one or more embodiments to improve output voltage ripple, as both outputs are being supplied at the same time, compared to prior art SIDO operation, where only one output is supplied for a given phase.
