Hi Bidault,
Did you already look at this reference design on the TPS62740 product page? It looks exactly like what you describe: http://www.ti.com/tool/PMP9753
There isn't such a low Iq device which gives a higher Vout, so you'll need to use 3.3V or…
Hi Terry,
Yes, some customers would use 2 series cells with the TPS62745.
Otherwise, you need to store enough energy in capacitors to ride through your pulse. Here's one way to do it: http://www.ti.com/tool/PMP9763
Since your output power is…
Ah, this is a very special lithium thionyl chloride cell. Yes, it has a very flat voltage but this varies a lot based on temperature and loading.
Here's a reference design we did for one of these, where it needs to power something very strong like a…
