Hello again,

[quote user="ustire@Nordic"]Also any ideas on the first part of my question in relation to using the PPK 2 with voltages above 5V?[/quote]

Seems to be limited to 5V yes, ref:

Hi Kenneth. Thank you for the response. The current out of the LED driver is supposed to be determined by an external resistor connected between 2 pins on the Driver. I used a value that per the data sheet should be close to 30mA which is close to the If of the LED. see snap shot below

My Vout is within the 1.4 to 5.4V range so I should be getting the about the same current per the graph above.

Also any ideas on the first part of my question in relation to using the PPK 2 with voltages above 5V?

Thank you

Hello,

I think this question is best addressed to infinion? It could be interesting to know what the current is out of the LED driver in these cases also.
