Possible alternatives to ADP5360

[WaStefan]

Hello everyone,

I am currently in the process of designing a prototype using the nRF9160 and I use the Nordic-Thingy91 as a reference for some parts.
The Thingy91 uses the ADP5360 for charging and power management.

Unfortunatly the ADP5360 only comes in a tiny BGA package, which is too expensive and inconvinient for a simple prototype for evaluation.

Now I'm looking for an alternative with similar functionality.

I have found the ADP5350 offers similar functionality and comes in a bigger package.

Are there any other good alternatives with these kind of functionality for low-power?

Thank you!

With the ADP5350 I could use the V_ISOS pin in the same manner as the V_SYS pin with the ADP5360 to power the nRF9160 right?

Looking at the ADP5350 block diagram V_ISOS seems to be the output of the DCDC converter, so it should be capable of supplying the nRF91. You can see that V_ISOS feeds into the other LDO's for the optional supply outputs (VOUT1-3). You should ask Analog Devices though, as it is their product and not ours they are the ones who know the most about how these devices operate.

Thank you for your reply, I will use it like that and hope for the best ^^

I did ask Analog Devices, but they haven't replied yet...
