  • RE: MC34063A: About the voltage drop across the sense resistor(Rsc)

    Resolved
    About LM2578A, The switch current limit is 0.75A. So it is not matched to their condition (Iout=0.5A).

  • RE: True negative supply

    You are looking at various older controllers such as LM2578A, LM34063A, TL5001A, TL1491A, etc. I don't think any of them have power good function.

  • RE: LM120: Need PDN (Part Discontinuation Notice) for obsolete LM120K-5.0 version of base part and also need its replacement or a cross

    Hey Dan, LM120K-5.0/883 is indeed obsolete. I've attached the PDN. We don't have an exact P2P replacement so I'd recommend the UA79 series as the closest alternatives. ~ Aaron PDN 200824.pdf
