TPS40195 and CSD86350Q5D (Synchronous Buck NexFET™ Power Block MOSFET Pair)

SwitcherPro doesn't know anything about the CSD86350Q5D.  I tried entering the part in My Library as a Q1 and Q2 sections, since the Sync and Control FET sections are very different from each other. 

SwitcherPro seemed to be happy with this method, but the thermal calculations are going to be wrong. I am not sure how to fix that.

The Switcher Pro team is working on adding this device to the tool, but I don't know the release schedule.  Your method is good.  My recommendation for the thermals is to add the power dissipation for the two MOSFET from the stress page.  This should be the total power dissipation for the two FETs together.  Peak power dissipation doesn't occur at the same point (High-side FET has higest power dissipation at low line typically, while the low-side FET has highest power dissipation at high line typically) but this slight over-estimation should help canceal the increased Rdson due to mutual heating in a common package.

Also, there are a LOT of errors in the Standard MOSFET library - a number of entries have, for instance, 10000 for the Rdson@2.5V.  I think the entry person just punted instead of looking at the charts.

I believe when no information was available at 2.5V, 10k was used as a default.  This could result in an error in the Rdson calculation for drive voltages under 4.5V when a linear approimation between 2.5V and 4.5V is used to estimate the mid Rdson.  This would result in Switcher Pro not picking devices not specified at 2.5V for a < 4.5V application.

And, in the Inductors, COEV (part of Tyco) parts are all EOL.

Thank you for the information, I will let our Switcher Pro team know.
