I recently used the LM2585SX-ADJ/NOPB for a small flyback design, I have another application in which I would like to use the same design, but the application requires operation down to -55C and the device is rated for -40 to 125C. Looking at the notes below the maximum ratings it says: "(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications." Can you provide a link to who exactly I should contact at the sales office? I would think there would be a way to navigate to somewhere I could check into availability of extended temperature range parts on TI's website but I have been unable to find it.
