Abstract:
1. A method for regulating an output voltage applied to a load at an output terminal of a power converter, the power converter including an output capacitor coupled between the output terminal and a ground reference, an inductor that is selectably coupled by a switch between a power supply and the ground reference, the method comprising: storing a power event and a corresponding open loop response in a memory device; sensing the output voltage and a current in the inductor during a plurality of time intervals; for each time interval: storing the sensed output voltage and the sensed current in the memory device; and comparing if the sensed output voltages and the sensed currents of one or more previous time intervals stored in the memory device matches the stored power event; wherein, when a match is not found, a close loop response is provided, comprising: wherein, when a match is found: applying the corresponding open loop response.
