LM5006: Drop in replacement

David Dean

Part Number: LM5006
Other Parts Discussed in Thread: LM34923, , LMR38010, LM5007

I am currently using LM5006 in a product. I am using the flyback diode, rather than a synchronous FET, so the LG pin is not connected. I have recently found LM34923 and, since I am not using the LG pin, this seems to be a drop-in replacement. Can you confirm that this will be fully compatible with the LM5006? Ideally including any EMI behavior?

Hi David,

LM34923 can be drop-in replacement for LM5006 if LG pin not used, EMI performance should be similar.

Thank you! Are there any other drop-in options for LM5006?

Hi David,

No other P2P replacement for LM5006.

Other possible parts are LM5007 or LMR38010

The LM5007 is out because I need the lower UVLO of the LM5006 (typ 4V).

LMR38010 is interesting. I am familiar with other parts in the LMR36x family. Is this part similar to those, but with an 80V max? In any case, LMR38010 looks to be unavailable, similar to those other LMR36x components...

HI David,

LMR38010 is newly released part:

It's similar to the LMR360XX with 80V rating.
