METHODS AND APPARATUS FOR DYNAMICALLY RECONFIGURING A CHARGE PUMP DURING OUTPUT TRANSIENTS

摘要

Methods and apparatus are described for dynamically controlling a charge pump system including a plurality of charge pump stages, with each charge pump stage coupled between an input voltage VIN at an input voltage node and an output voltage VOUT at an output voltage node. In particular, the configuration of the charge pump stages may be dynamically controlled during a transition on VOUT from a first voltage to a second voltage to improve the circuit's transient response.
