  • LM2731: LM2731XMF/NOPB

    Resolved
    Part Number: LM2731 Hello everyone, I was wondering if the LM2731XMF/NOPB can output a voltage higher than the 20V max if I reference ground to a higher voltage. Let's say I have 50V at Vin and a ground reference of 40V, would the device the the input…

  • RE: WEBENCH® Tools/LM2731: LM2731 efficiency calculation in WEBENCH

    Resolved
    Hi Bhushan, Thanks for the quick reply. In the LM2731 datasheet, there is efficiency curve figure 16 for X option and figure 23 for Y option. The 30mA efficiency is much less than 91.9% if fsw = 1.6MHz. The 30mA efficiency will higher if using fsw…

  • RE: LM2731: Vout when SHDN=0V (shutdown functionality)

    Resolved
    Hi Matos, LM2731 doesn't support true shutdown function (Vout=0V) because it's non-synchronous boost converter. When SHDN=0V, there is no switching but the Vin will charge the output capacitor through inductor L, rectifying diode until Vout reaches…
