Methods and apparatus to calibrate a power converter

Abstract:

Methods, apparatus, systems and articles of manufacture are disclosed to calibrate a power converter. An example apparatus includes a comparator including a first input terminal, a second input terminal, and an output terminal, the first input terminal of the comparator configured to be coupled to a filter to receive a filtered feedback signal, the second input terminal of the comparator configured to receive a first voltage signal, and the output terminal of the comparator coupled to a node, an oscillator including an output terminal, and a voltage stepper including a first input terminal, a second input terminal, and an output terminal, the first input terminal of the voltage stepper configured to receive a second voltage signal, the second input terminal of the voltage stepper coupled to the output terminal of the oscillator, and the output terminal of the voltage stepper configured to be coupled to an error amplifier.
