1. A charge pump controller comprising:
- a switch matrix having a plurality of switch configuration modes, the switch matrix configured to receive an input voltage and form an output voltage that is a multiple of the input voltage and configured to supply the output voltage and a load current to a load; and
a current controller configured to receive a sense signal that is representative of the load current and form a mode control signal to set an operating mode of the switch matrix responsively to a first value of the load current.
