Part Number: TPS55340

Hi Team,

I tried the following input with TPS55340 but output schematic shows LM3478 as the following.

Is it bug for WEBENCH?
My customer wants to simulate WEBENCH with TPS55340.

Yaita-san,

We have only modeled the boost topology for the TPS55340 in WEBENCH Power Designer. It is not currently possible to simulate the TPS55340 in a SEPIC topology in the tool. Please use the WEBENCH Visualizer to see alternative options for your Vin=4.2-21V, Vout=5V, Iout=1A design.

We are looking into the issue where the LM3478 SEPIC is showing in the tool when trying to launch the TPS55340 WEBENCH panel and will reply here when we have an update.

Regards,
Kris

The issue of the LM3478 schematic appearing has been resolved, but to reiterate, WEBENCH Power Designer only supports the boost topology for the TPS55340 and the above design condition cannot be designed in the tool.
