Dear TI,

First of all, thank you very much for your super supports Travis and Nini,. I would not be able to go this far without you.

I have tested the system with TPS61027 and I noticed that the system performance is not good. At first I thought that the layout of the circuit is not good (which it was for the one I posted in a previous thread).

However, what plays a bigger role in my case is that I use TPS 61027 for charing LI-ION battery (which requires more than 300 mA) and TPS61025 which handle pulses of current for the Radio antenna (which can exceed 200 mA).

So, I wonder if there is a chip that can boost from 0.8 or 0.9V to 5V and 3.3V with higher current than 200 mA? I know efficiency will probably a trade off, but consistent function crucial for me.

Thank you very much for your time,

Khoi
