Abstract
A controller may be configured to generate a control signal to activate and deactivate a switch of a switching power converter in order to control a switching period and a peak current of the switching power converter to maintain a regulated current of the switching power converter at a desired current level such that: if the switching period decreases below a minimum switching period, the controller increases the switching period by a ringing period of a voltage of the switch and increases the peak current to compensate for the increase of the switching period in order to maintain the regulated current, and if the peak current increases above a maximum peak current, the controller decreases the switching period by a ringing period of the voltage of the switch and decreases the peak current to compensate for the decrease of the switching period in order to maintain the regulated current.
