Cycle skipping
At very low power levels, a cycle skipping mode will be
activated. A high control voltage will reduce the switching
frequency to a minimum of 25 kHz. If the voltage on the
control pin is raised even more, switch-on of the external
power MOSFET will be inhibited until the voltage on the
control pin has dropped to a lower value again (see Fig.8).
For system accuracy, it is not the absolute voltage on the
control pin that will trigger the cycle skipping mode, but a
signal derived from the internal VCO will be used.
Remark: If the no-load requirement of the system is such
that the output voltage can be regulated to its intended
level at a switching frequency of 25 kHz or above, the
cycle skipping mode will not be activated.
