Abstract
These teachings apply with respect to a direct current (DC)-output converter and provide for adjusting a number of switching pulses per burst cycle as a function, at least in part, of converter output loading. This adjustment can be made by controlling burst frequency with respect to at least one predetermined threshold frequency. The predetermined threshold frequency can comprise a non-audible frequency such that the number of switching pulses is adjusted to prevent the burst frequency from itself constituting an audible signal. The adjustment of the number of switching pulses per burst cycle may only occur when the output loading is less than a predetermined level of loading. These teachings may also provide for clamping the pulse frequency for the pulses in each burst package to a particular value when dynamically controlling the number of pulses in each burst package. The aforementioned particular value may constitute, for example, a highest available switching frequency.
