Abstract
Startup operation of a DC/DC switching regulator is controlled by providing a first signal (MAXDC) whose waveform has a duty cycle that varies over time, providing a second signal (620, 622) indicative of a load condition of the regulator, and combining the first and second signals to produce a third signal (312, 311). The third signal is used to control a power switch (231, 324) of the regulator.
