Abstract:
1. A power converter comprising: a high-side switch coupled to a power supply terminal and selectively coupled to ground via a conduction path, wherein said high-side switch is enabled and said conduction path is disabled during an on state duration, and wherein said high-side switch is disabled and said conduction path is enabled during an off state duration, and wherein said high-side switch and said conduction path both are disabled during a skip state duration; and a controller coupled to said high-side switch and configured to calculate said skip state duration based on a predetermined current reference and an equation, and configured to generate a first control signal for controlling said high-side switch and said conduction path according to said on state duration and said skip state duration that is calculated based on said predetermined current reference and said equation, and configured to adjust an output current of said power converter to said predetermined current reference by controlling said high-side switch and said conduction path using said first control signal.
