ABSTRACT:
The present invention uses a multi-phase oscillator or a mono-stable circuit in order to charge the output instantly or within an acceptable time period when a charge pump circuit is in a PFM mode and an output voltage is below a preset voltage level. Therefore, the present invention avoids the problem of charging the output in an unacceptable time delay thereby achieving the advantage of reducing the voltage ripple at the output.
