ADP2300 PFM/PWM mode

Hi,

I have a queston about ADP2300.
The Datasheet says this device has the automatic transition between PFM and PWM.
But I want to konw how much output curennt trigers PFM mode in general.
Because this device is usd for the analog circuit directly in my system.

I know the transition current depends on Vin, Vout and inductor.
But it would be great if there is a way to predict it.

Best regards,
Tarzan
