TOPSwitch-jx and auxiliary coil in no load

Hello,

I wish to design an offline TOPSwitch-jx Flyback SMPS which can draw < 500mW in no-load.
I wish to take advantage of the topswitch-jx multi-cycle-mode to achieve this.

however, as described on page 19 of this literature..........

(LHS of page 19, 1/2 way down)

"Self-supplying controllers in extremely low standby
applications often puzzles the designer. Actually, if a
SMPS operated at nominal load can deliver an auxiliary
voltage of an arbitrary 16 V (Vnom), this voltage can drop
below 10 V (Vstby) when entering standby. This is because
the recurrence of the switching pulses expands so much that
the low frequency re-fueling rate of the VCC capacitor is
not enough to keep a proper auxiliary voltage."

Have you specific powerint.com application notes where you address this drop-out of the auxiliary coil voltage?
