LM2596: Output cap: aluminium or tantalum at minus 40 C in WEBENCH

Part Number: LM2596
Other Parts Discussed in Thread: LM2670, LM2672, LMR23630, LMR33620, LM22670, LM2595

Dear Frank, dear Carol, good morning.

Gentlemen, excuse my persistence.

1) I choose the temperature plus 85C in WEBENCH, but I need a range of minus 40 to plus 85. Can I set the temperature minus 40 in the  WEBENCH?

2) If I chose in WEBENCH plus 85 C temperature and the program installed an aluminum capacitor at the output, does the program take into account the fact that the circuit should operate at a temperature of minus 40 C too?

3) Please, recommend me IC (not very expensive and widely used), which can operate with ceramic cap output only. I need 5V & 2A out and 12 V & 1A out. Input voltage is 22 - 32 V.  Power supply circuit should be approximately the same as LM2596. 

TIA

Sincerely,

Vladimir Naumenkov
