Abstract
Methods, apparatus, systems and articles of manufacture are disclosed to start converter into a pre-biased voltage. The disclosed methods, apparatus, systems and articles of manufacture provide an apparatus comprising: an error amplifier including a feedback network and a differential difference amplifier (DDA), the DDA coupled to a power converter, a voltage generator, and the feedback network coupled to the third input of the DDA, the fourth input of the DDA, and the output of the DDA; a multiplexer coupled to the voltage generator, the second input of the DDA, and the first input of the DDA; a first switch coupled in parallel to the feedback network; a second switch coupled to a delay cell and an oscillator; and a trigger including an output, the trigger coupled to the voltage generator, the power converter, and the output of the trigger coupled to the multiplexer, first switch, and the second switch.
