WEBENCH® Tools/TPS65261-1: Implementing a design seems to be broken

Hi,

Let me check it and update you later.

Hi,

TPS65261 was released on Dec. 2013 and of course in mass production now.

Todat I check it with Webench and no problem with simulation.

Was your operation condition out of TPS65261 rating?

Sorry for my misleading question stating "not listed". I give you some more details.

I tried following parameters for a design:

Vin 1-3 = 4.5 - 15V

Vout1 3.3V 2.00A

Vout2 2.5V 1.50A

Vout3 5.0V 1.00A

Ambient = 85

Open Design opens the Webbench Designer an I see "Initializing" and "loading" and then "Design Cannot Be Created"

I f I use "Show Why Parts Were Not Found" a Window opens where I see Vin 14 to 22 which is not what I wanted to simulate.

Only the default settings on the websites create a valid design. Changing some

If I try to create a new design inside the Webbench Tool using "See all Devices" the TPS65261 is not listed.

Thank you for your support, Alfred

Hi, thank you for your help.

Did you get any feedback from the model team?

I gave Webbench a try today but without success. I have to finalize my PSU which should use two of the TPS65261-1.

Thank you,

Hi, Alfred

I haven't got feedback from model team, i will push them, sorry for late.

Before getting feedback, I recommend to start your design on the base of TI reference design, which is validated by many tests.

Below is TPS65261-1 EVM reference design.

Hi, Alfred

We are misled by error information "Vin 14 to 22 ".

Due to Vout3=5V, when you create design, you need to set min Vin1~3 is bigger than 5V.
And due to maximum duty limitation, you'd better set min Vin>=5.5V.
