LM63615-Q1: Efficiency, line regulation & Load regulation data @ temperature -40C,105C

Hello

What output voltage, switching frequency and inductor are you using.

Thanks

hello frank

output voltage : 3.3V

switching freq : 2.1MHz

inductor : 4.7uH

Hello

I will look and see if we have any data that is close to those specifications.

I will get back to you by early next week.

Thanks

Hi Frank,

thanks for the fast feedback ! 

thank u frank for fast reply

hello frank,

Can you please help me to similar data for TPS6281120QWRWYRQ1

Hello Dasthahir,

I need to forward this to my colleagues whom support this device.

Hi Dasthahir,

Thanks for your question.

I would advise you to refer to our Webench model to get the required data (Power Designer (ti.com)).

Here you can select your customize your BOM and easily obtain the efficiency plots, tuning VIN and temperature as desired.

Please ask again if you have further questions.

Thanks,

Stefano.

As per WEBBECH the simulation is not enabled for this part(TPS62811) , so i cannot take efficiency data

Please help me to find the data

Hi Dasthahir,

I would advise you the Webench model for TPS62810-Q1 (Power Designer (ti.com)).

I would not expect significative differences in terms of efficiency.

If you want you can also refer to the PSpice model of TPS62811-Q1 that you find on the product page (TPS62811-Q1 data sheet, product information and support | TI.com).

However, I would advise the Webench model, since it is much faster and easier for efficiency computation.

Thanks,

Stefano 

Hi Dasthahir,

I have just checked, and it seems that you can still read the efficiency and other parameters even if the Webench simulation is disabled.

Please refer to below figure.

Thanks,

Stefano 

hello Stefano

Thank u for the information

Please let me know one more information, if we are doing the simulation,which option we need to select for getting Efficiency curve

Hi Dasthahir,

Thanks for your question.

The TPS62812-Q1 Webench model is again online. I would advise to use it, since the 2A version is very similar to TPS62811-Q1. This would give you more accurate results.

Regarding the simulation, you can select steady-state and then see the efficiency curve in the export tab (Power Designer (ti.com)).

In the above simulation, feel free to modify the BOM as needed.

Thanks,

Stefano
