Dear Brigitte,
I used the LM5177EVM-HP and yes I have used the calculation tool to find suitable and stable values. This is how I modified the EVM which functions properly.
Kind regards,
Robin.
Hi Allen,
the LM51770 would fit here very well.
A good starting point would be the EVM:

(Note: this EVM is still using the LM5177 which is pin compatible with the LM51770. Would recommend to use the LM51770…
Hello Robin,
I am very sorry that you have issues with the EVM. Could you please use the Quickstart calculator to calculate the necessary changes for your specific requirements? SNVR519 Calculation tool | TI.com
BTW, I would as well recommend using…
Part Number: LM5177 Dear,
I was testing the LM5177EVM-HP module to see if the design was applicable with modifications for our application. I initially tested in the default setup which worked fine.
Two modifications were made: - Feedback resistors…
Hi Romek,
it is not easy to see as the scaling is still a little bit high but i think the dead time is OK.
For the first image above (" Gate Oscillogram on Q48 and Q51") it is still strange that the edges looks much slower then for the others.
It…
Part Number: LM5177 Tool/software: Hello,
We are considering using the LM5177 controller with GANFETs to build a BUCK-BOOST. Design requirements: Vin = 6V to 50V, Vout = 28V, and Iout(max) = 25Amps when VIN=24V to 50V, We are limited to 60Amps on…
Hi Adam,
there is either one of the MOSFET driver pins having a to high load, e.g. due to a damaged MOSFET or the LM5177 might be damaged.
For the LM5177 this could happen if there are over or undershoots on the SW which lead to an overcharge of the…
Hi,
We current don't have a BBU reference design released. Maybe LM5177 EVM can be a starting point?

Hello Sam,
I am sorry, but I am not sure what you are searching for. Would it possibly help to review the schematic of the EVM? LM5177EVM-HP Evaluation board | TI.com
Best regards, Brigitte
Hello,
Thanks for reaching out. Could you please share the link of the schematic or user's guide of this board? It does not look like the LM5177EVM-HP. We're looking forward to hearing back from you.
Kind regards, EM
