Tool/software:
Hi, I used TPS65217CRSLR in my ongoing project, and I planned this IC to supply power to wireless/rf module. (Quectel EC200U)
I wonder the max.current / max. peak current capability of TPS65217CRSLR SYS pins.
This module may reach 2.7A during transmission.
Thank you for answer.

Omer
Hi Omer,
The max input current actually depends on some register settings and the input pin you are using on the IC.
The AC pin has the highest current limit setting. The AC input current limit can be set up to 2.5A:
The SYS pin can handle all these different settings and should not become the limiting factor during operation.
However, none of the outputs on this device have a max current capable of 2.7A, so between the input current limits and the output current limits of the BUCKs I don't think this IC would work for your application.
Something like the TPS65219 might be worth checking instead.

James
