Lowering the Standby Power with SkipCycle
Skipcycle offers an efficient way to reduce the standby
power by skipping unwanted cycles at light loads.
However, the recurrent frequency in skip often enters the
audible range and a high peak current obviously generates
acoustic noise in the transformer. The noise takes its origins
in the resonance of the transformer mechanical structure
which is excited by the skipping pulses. A possible
solution, successfully implemented in the NCP1200 series,
also authorizes skipcycle but only when the power
demand has dropped below a given level. At this time, the
peak current is reduced and no noise can be heard.
Figure 20 pictures the peak current evolution of the
NCP101X entering standby.
