LM2597HV: LM2597HVN-ADJ/NOPB as LM2594HVN-ADJ/NOPB alternate source

Part Number: LM2597HV
Other Parts Discussed in Thread: LM2597

Hi Team,

My customer is looking for alternate source to LM2594HVN-ADJ/NOPB due to supply situation, can you please advise on the following comparing this device to LM2597HVN-ADJ/NOPB? Thanks!

Comparing the two devices electrically, here are the differences I see:

  • Can the Error_Flag, Delay and Bias_Supply pins on LM2597 be left floating?
  • Is the enable pin logic the same, or does it need to be flipped (/SHUTDOWN vs. /ON)? 
  • Datasheet shows the SOIC vs. PDIP junction to ambient thermal resistance values as being flipped in the respective datasheets, can you advise? 
  • Any other electrical, pinout, or package differences we should be aware of?

Best Regards,
