Configurable multi-output charge pump

A charge pump, comprising:

• charging circuitry including one or more flying capacitors (FCs) arranged to be switchably connected into a plurality of circuit configurations, each operative to provide at a common charging node a voltage that is a multiple of an input voltage;
• storage capacitor circuitry including one or more storage capacitors (SCs), each arranged to be switchably connected to the common charging node, wherein an SC is operative to be charged to a particular voltage depending on which circuit configuration of the charging circuitry is driving the common charging node, each SC adapted to supply a respective voltage output at a corresponding output node associated therewith;
• a mapping selection logic circuit for generating one or more output selection signals operating to actuate a particular combination of one or more selection switches to control which SC is connected to the common charging node for a configurable amount of time;
• and
• a configuration logic circuit for generating one or more configuration setting control signals to actuate a particular combination of one or more configuration switches to connect a select set of FCs for each circuit configuration of the charging circuitry, wherein the configuration logic circuit is operative to effectuate a charge phase connection state and a storage phase connection state for said each circuit configuration, the configuration logic circuit further operating responsive to which SC is selected to be connected to the common charging node, thereby effectuating a corresponding circuit configuration for generating a particular multiple of the input voltage at the common charging node.
