I have a number of questions, relating to different power devices & topologies. Firstly, I note that you have a 'one eighth' brick design using the LM5046 devices. I see no clarifiaction of a part number for T1 in that design, or any other documentation. Do you have that information available? (Application Note 2126 LM5046 Based Eighth Brick Reference Design)
Also, I have another requirement for a high voltage, high temperature solution. The device UC1844A looks very interesting, but unfortunately is not available in a high temperature version.
Can someone advise me who would be the best application engineer/ 'guru' to speak to at Ti, in relation to these & other devices?
