Abstract
Operating DC to DC power converters. At least some of the example embodiments are methods including: driving current through an inductance in a first on cycle of the power converter; comparing, by a comparator, a signal indicative of current through the inductance coupled to a first input of the comparator to a threshold applied to a second input of the comparator, and asserting a comparator output responsive to the signal indicative of current meeting the threshold; sampling a differential voltage across the first and second inputs, the sampling responsive to assertion of a comparator output, and the differential voltage indicative of propagation delay through the comparator; and compensating the comparator in a second on cycle for the compensation delay based on the differential voltage, the second on cycle subsequent to the first on cycle.
