TPS61322: Selection of components

Part Number: TPS61322
Other Parts Discussed in Thread: TPS61021A

Hello,

I am designing a power supply for a module which require msximum of 700mA and a voltage of 3.6V. So I think TPS613226A is a good choice. How can I control the ouput current limit? Is it mostly dependent on saturation current inductor? I dony have information on maximum ripple allowed.

Regards,

Hi Prudhvi,

What is the input voltage range, or the minimum input voltage? is the output condition 3.6V and 700mA?

Hello,
The minimum voltage can be taken as 2V as extreme. Yes the output condition is 3.6V and 700mA.

Hi Prudhvi,

The device can't support such high output current from 2V input, I would suggest TPS61021A

Hi Prudhvi,

from 2.5V output voltage, the output current of the TPS613226A should be lower than 350mA. that is why i suggest TPS61021A for 700mA output current requirement.
