Claim 0:
1. A method to operate a DC-DC power converter in a low power burst mode, the method comprising:
sampling an output voltage of the DC-DC power converter with a sampling frequency to determine when to initiate a burst for the low power burst mode; and
adapting the sampling frequency based on the output voltage, adapting comprising:
incrementing an up counter in response to the burst being initiated,
resetting the up counter in response to the burst not being initiated,
incrementing a saturating up-and-down counter upon receipt of an overflow signal from the up counter,
decrementing the up counter in response to the up counter being reset, and
selecting the sampling frequency according to a count of the saturating up-and-down counter.
