Abstract
A pump system that can dynamically increase its current capability includes: a pump circuit, for producing an output voltage; an oscillator, for driving the pump circuit to pump at a particular frequency according to a pump enable signal; a limiter, coupled to both the oscillator and the output voltage fed back from the pump circuit, for generating the pump enable signal to the oscillator according to the output voltage feedback signal; and an edge timer, coupled to both the oscillator and the pump enable signal, for driving the oscillator to operate at an increased frequency according to a threshold parameter of the pump enable signal.
