What's the difference between LM5143-Q1 and LM5143A-Q1?  I didn't find the difference on datasheets. Thanks. 

  • Hi Wayne,

    The A version here has equivalent silicon and PCB layout. However, it's on 300mm fab and in-house test/assembly, so much better availability in this tight supply environment. Note we have also released the LM25143-Q1 (42V max Vin version) as well as the LM5143 and LM25143 commercial versions.
