Dear Support, I've got the same question: is the TINA model available for this device ?

Thanks in advance for support

Best regards.

Hi Gianluca:

We have TPS61020 TINA model available. The mainly difference is the current capability.

May I know if it is ok for you?

Hi Minqiu,

thanks, but I downloaded TI model Library and already have model of TPS61020.

In order to try a more precise simulation I was looking for TPS61029-Q1 or TPS61029. Unfortunately none of them is included in the library, nor available in Webench.

Best Regards

Hi Gianluca:

So sorry that we don't have TPS61029 version. But in other words, it's not a good idea to simulate the worst case. The tolerance of the current limit is little wide. As 1.5A minimum and 2.1A maximum.

May I know what's your Vin, Vout range, load condition and inductance value? So that I can help to check if the TPS61029 has such current capability.

Hi Minqiu,

please find information herewith in the following:

Vin range: 2V9-3V3

Vout: 5V

Load: current pulses < 1A peak pulses.

Inductance: 6.8uH

Current capability of TPS61029 should not be an issue because it's derived from other projects and in this particular one is over-sized.

I think I could proceed using model of TPS61020, because they're quite similar.

Best regards.

Gianluca
