LM51561H-Q1: Pulse skip mode when light load

Part Number: LM51561H-Q1
Other Parts Discussed in Thread: LM5156H-Q1, LM5156

Hello Flyback Controller Team,

My customer try to use LM5156H-Q1 with PSR fly-back.

The load current (secondary side) is very wide as 50mA to 600mA, does LM5156 have pulse-skip at light load condition?

If yes, what(s the condition to be in the pulse-skip mode.
