https://devzone.nordicsemi.com/f/nordic-q-a/75527/ppk2-handling-of-in-rush-currentsHi, I have a card with some large capacitors in parallel with the VBAT line. How does the PPK2 work (in source mode) at board start-up where there might be a short in-rush current that might exceed the rated 1A? Does it limit the output current to 1Aen-USTelligent Community 13Wed, 26 May 2021 09:29:31 GMThttps://devzone.nordicsemi.com/thread/311703?ContentTypeID=1Wed, 26 May 2021 09:29:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8db51cb7-c9d2-4fdc-b3be-b931b2a26ceePema<p>Ok, thanks.</p> <p>Peter</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/311699?ContentTypeID=1Wed, 26 May 2021 09:18:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ffaf4350-bf34-4dac-bf99-f9d006a77301awneil[quote userid="2125" url="~/f/nordic-q-a/75527/ppk2-handling-of-in-rush-currents/311683#311683"]The kit will manage fine at least up to 2-3 A inrush current.
