Abstract
A method of controlling a start-up sequence of a DC/DC Buck converter includes continuously comparing the Buck converter's output voltage with an internal reference voltage and continuously monitoring for a Buck converter start-up signal. If the output voltage is greater than the reference voltage when a Buck converter start-up signal is detected, the Buck converter is switched off and an output capacitor of the Buck converter is discharged through a pull-down unit until the output voltage substantially equals the internal reference voltage and then restarting the Buck converter.
