Hello,
I am interested in using this high temperature buck controller for an application that needs to power components at 180C ambient (its an R&D project for a manufacturing company). The TPS40200-HT datasheet, however, is a gate driver for a PFET. I have not been able to find any PFETs that will be able to survive a 180C ambient. Is this truly the case? Because then I'm wondering why the controller goes up to such high temperatures if none of the FETs can go that high anyways.
If no such PFETs exist, is there a recommended solution or reference design in which TI has successfully used this controller at temperatures that high?
Thanks in advance for the help.
Best regards,
Theo
