TPS63806: Find suitable Low VIN/ 3A buck boost converter

Hi Team,

My customer is surveying our buck-boost solution now,

They need:

1. Input voltage : 1 cell battery (3V~4.4V)
2. Output voltage : fixed 3.3V
3. Output current : Imax = 3A

After I search on TI.com, I think the TPS63806 may be the right solution, but the Iout max is 2.5A,

If I want to find a larger solution, our product map will jump to a 16A solution TPS552882, that will be a over spec solution for customer.

So do you have any other better solution ? Or do you think TPS63806 can support up to 3A ?

Thanks!

Kai
