I found in the library that Bootstrap is not supported at all. Then I wonder why the BST pins are listed at all and why they cause problems with the simulation.

Hi Michael,

Thanks for reaching out.

I will look into this and reply to you tomorrow.

Hello Bryce,
thank you very much for your feedback. Floating pins generate an error and the simulation does not even start. Can I connect the pins to GND or short them together?

Best regards

Hi Michael,

The project works properly with the project I downloaded from the product page, can you modify the parameters based on that project and start the simulation again?

Hello Bryce,
I downloaded exactly this ZIP archive, but created my own project and then integrated the library and the model into my project.

I'll use the finished project in a moment.

For your information. Shorting against GND has helped and delivered a result.

Without connection.

Kind regards

Result of my own project with shorted BST1 & 2 to GND.

Hello Bryce,
I have one more question. How can I configure the simulation so that I get 12 V fixed voltage at the output? My circuit has been designed according to TI Webbench with the aim of buck/boost for 12 volts with an input voltage of 9 V to 30 V.

I still get 5 V at the output

Kind regards

Hi Michael,

Please try to connect VOS_FB to VREG to select 12V output voltage.

BRs,

Bryce
