Abstract
A mode transitioning system ( ) for a charge pump ( ), which may optionally be embodied in an integrated circuit ( ). A number of switches ( ) are operated based on an input detection sub-circuit ( ) and an output detection sub-circuit ( ) to controllably connect a number of flying capacitors ( ) in a variety of manners producing alternate input voltage to output voltage step ratios. One example embodiment of the mode transitioning system ( ) proceeds from an idle state ( ), through start-up and fault testing states ( ), and then selects among alternate step-down ratios of 1:1, 2:3, and 1:2 based on suitability and efficiency for respective operating states ( ).
