Tool/software:

Hey Buck-Boost Converter team,

I have a customer evaluating the new TPS552872 for a new design and we noticed that it is not currently supported on WEBENCH.

Is there plans for this device to be supported in WEBENCH? How can customers begin their evaluation and simulation testing today?

Any guidance you can provide would be much appreciated!

Best regards,

Matt Calvo

Hi Matt,

Thanks for reaching out.

1. Currently we have not released the Webench for TPS552892/72, and the plan is not decided. Could the customer use the TPS55289 Webench and the attached calculation tool instead? And please send the schematic and layout to us for review when finished.

2. The PSpice model of TPS552892 is ready and has been released to ti.com, the customer can also use that for simulation. TPS552892 and TPS552872 is P2P and only the average inductor current limit (TPS552892: 8A, TPS552872: 4A) is different.
