I read Datasheet of ADP2311.(Rev.A)
I have a question about the "Temperature Range" which appears on an ordering guide.
Is this prescribed by the junction temperature?
Or is this prescribed by ambient temperature?

Best regards,

Please inform me about how to use ADP2311.
When not using a PFO pin aggressively, how should a PFI pin be connected?
For example can I tie PVIN1 pin and a PFI pin?

Or isn't such directions permitted?

Regards,

I checked ADP2311 datasheet.

The efficient chart when being in case of Vin=12V and Vin=5V, is shown to a datasheet.

Is there an efficient chart in Vin=4.5V or Vin=4.6V?

Or is there a simulator of ADP2311?

Advice, please.
