  • RE: LM5156H: High power output

    Resolved
    Hi Kaiji, Thanks for using E2E! As the power level is quite high, sync controller will be recommended on this. You can refer to below reference design based on 2-phase LM5122, which is built in SEPIC topology to avoid the VOUT limitation. The Vout…

  • RE: LM5122-Q1: Need Help with 3A 100V design on LM5122

    Hi Joseph, Unfortunately, I did not find a reference design that does match your specs. The closest input/output parameter match was with a SEPIC design, where LM5122 is used asynchronous, meaning SW pin is connected GND and diodes are used instead…
