<p>A method of controlling a start-up sequence of a DC/DC Buck converter, the method being characterised by the steps of continuously comparing the Buck converter's output voltage with an internal reference voltage and continuously monitoring for a Buck converter start-up signal, wherein if the output voltage is greater than the reference voltage when a Buck converter start-up signal is detected, switching off the Buck converter and discharging an output capacitor of the Buck converter through a pull-down unit until the output voltage substantially equals the internal reference voltage and then restarting the Buck converter.</p> |
