  • LM5574

    LM5574- Using WebBench, I made an inverting switcher using the LM 5574. The parameters I used were 7<Vin<9.5, Io (max) = .015A. The resultant circuit initially didn't function at all. I ran WebBench again using an alomost identical part (LM5575...

    Hi all, I have a question. LM5574 has 76V maximum voltage input. I didn't find the limiting minus

  • RE: Question about LM5574 maximum rating (SW to GND)

    Hi Satoshi-san, I agree the Cin capacitors should be closer to the IC, especially the GND node of the caps. The current going through input capacitors in buck converter is discontinuous current. Minimizing the loop area from Vin pin to CIN caps back...
