  • LM5176: SW1 work on DCM mode with no load or light load

    Resolved
    Part Number: LM5176 Tool/software: Dears, LM5176 should be already CCM mode. but input voltage sets on Vin=18.5V~25V and Vout=12V, SW1 works on DCM mode. However, Vin=18.4V~9V and Vout=12V, SW1 or SW2 works on CCM mode. On DCM mode, PG has pulse issue…

  • LM5176: LM5176 Dead Time issue

    Part Number: LM5176 Tool/software: Hi, Based on LM5176EVM-HP schematic to design LM5176 12V buck 5V. But we found that the dead time was 45ns and may lead to the risk of MOSFET shut-through or blow up. How to adjust deadtime? Regards Hins Weng

  • RE: LM5176: LM5176

    Hi Stefan, After all these issue, finally we decided to use TI LM5176 EVM board for testing purpose and we observed below spike issue. We kept same components as TI EVM suggestion but with two mosfets CSD18540Q5B (at each side Q2,Q3,Q4,Q5,Q6,Q7 & Q8 all…
