The burst frequency becomes so low that it is difficult to keep an adequate level on the auxiliary VCC ... >30 ms Lowering the Standby Power with Skip--Cycle Skip--cycle 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 skip--cycle 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. |
