LM2678S-5.0/NOPB Thermal Shutdown

Hi TI,

At what junction temperature, LM2678S-5.0/NOPB part will get thermal shutdown?

 

My next question: if we use the two LM2678S-5.0/NOPB regulator for redundancy purpose for a single output supply, Shall i connect the feedback pins of both regulator to the output supply directly? Further informations are, two regulator will not work at same time. one regulator only work at a time and output of the each regulator is connected with series diode for each output connection to avoid regulator loading.

Please reply for my questions.

 

Thanks,

Sivaraman
