Abstract
A charge pump circuit has load driven clock frequency management. The charge pump circuit includes a CCO generating a CCO output signal that has a frequency generally proportional to a feedback current, and a charge pump operated by the CCO output signal and boosting a supply voltage to produce a charge pump output voltage at an output coupled to a load. A current sensing circuit senses a load current drawn by the load and generates the feedback current as having a magnitude that varies as a function of the sensed load current if a magnitude of the load current is between a lower load current threshold and an upper load current threshold. The magnitude of the feedback current does not vary with the sensed load current if the magnitude of the sensed load current is not between the lower load current threshold and the upper load current threshold.
