As the output load decreases (FB voltage decreases), the
valleys are incremented from the first to the fourth. When
the fourth valley is reached, if FB voltage further decreases
below 0.8 V, the controller enters VCO mode.
During VCO operation, the peak current continues to
decrease until it reaches 17.5% of the maximum peak
necessary output power. This allows achieving very low
standby power consumption.
The Figure 28 shows a simulation case where the output
current of a 19 V, 60 W adapter decreases from 2.8 A to
0.1 A. No instability is seen during the valley transitions
(Figures 29, 30, 31 and 32)
current: the switching frequency expands to deliver the
Figure 28. Output Load is Decreased from 2.8 A Down to 100 mA at 120 Vdc Input Voltage
