LM5576: LM5576MH, LM5576MH/NOPB, and LM5576MHX/NOPB differences

Hi Jasime

All devices are functionally equivalent.

The differences would stem from reel size or RoHS status.

Lastly, 

LM5013 is preferred for new applications. LM5576 is on an outdated process which has lower priority in our fabs.
