ABSTRACT:
A power converter for and method of producing a monotonic rise in output voltage at start-up. In one embodiment, the power converter includes a switch and an error amplifier coupled to an output terminal of the power converter. The power converter also includes a comparator with an output terminal coupled to a control terminal of the switch and an input terminal coupled to an output terminal of the error amplifier configured to enable the switch to conduct for a duty cycle. Additionally, the switch is configured to be turned off at a start-up of the power converter until a voltage of the output terminal of the error amplifier provides a duty cycle for the switch corresponding to an output characteristic pre-charge condition.
