HI TI,

I have two questions

First,

I just got a TPS61099EVM-768.

I hope to make 3.3V output with 3.0V input.

How can I make 3.3V output? Currently, it comes out with 5.0V.

If the evaluation board can not make 5.0V, is there any available EVB supporting 3.3V output with TPS61099x family?

Second,

I'm also looking at TPS610981. So, I want to compare two boosters.

If TPS610981 is compared with TPS610994, can you tell me which one will be better?

My application uses 10~70uA for long time, but sometimes it goes 45mA.

So, I'm thinking using the low power mode of TPS610981.

Thank you in advance.

Hi Tae:

Thanks for choosing TI.

For first question, the default Vout is 5V for the EVM. If you need 3.3V, you could change the R1 with 573kohm.

For the second one, both TPS61099 or TPS61098x could achieve the target. It seems you don't need the Vsub function of TPS61098x. So I would recommend to choose the TPS61099 family with smaller size solution.
