Abstract
A switching power supply controller for a switching power supply is provided that measures an input voltage through an application of a load during an input voltage measurement period following connection of the switching power supply to an AC mains. Based upon the measured input voltage, the controller adjusts a start-up delay period so that the start-up delay period is substantially constant despite variations in an AC line voltage for the AC mains.
