Part Number: TPS40170

Tool/software: WEBENCH® Design Tools

I could not simulate TPS40170 for the reason of calculated Duty cycle error, please see below;

Is there update schedule for improve ?

I want to use classic webench because require to customize compensation network.

Satoshi-san,

I will check to see where this is coming from.

In the meantime you can probably increase the VIN Min to allow the design to be created.

Satoshi-san,

The parts you show are -EP. Can you find the TPS40170 without the -EP? This works for me on WEBENCH.

Thank you for reply,

I tried to search TPS40170 without EP, but I didn't find TPS40170 on "classic" webench.
Could you consider to check based on TPS40170-EP?

I guess that TPS40170 and TPS40170-EP are same function and simulation results.

Best regards,
Satoshi

Satoshi-san,

The team is looking into this. I should have an answer by tomorrow.

Yes, TPS40170 and TPS40170-EP should have the same function and sim results.

Satoshi-san,

I was able to go to the TPS40170 product folder, open a new design in new WEBENCH, then open Classic WEBENCH and search in "My Designs" to open the TPS40170 in classic WEBENCH. The design appears to be working. This should work for you as well, let me know.
