  • TPS61098: PSPICE for TI TPS61098 wrong model

    Part Number: TPS61098 Hello team, I was trying to simulate TPS61098 with PSpice for TI and it seems to be that the model is not working well. I tried the simulation with SS = 0 and SS = 1. It seems to be that the parameter SS is either 0 or 1. SS…

  • TPS61098: Current limit

    Part Number: TPS61098 Hello team, I am wondering what is the current limit in the VBUS output pin in TPS610981 and TPS610986 chipset??? I denoted that load switch on resistance in TPS610985/6 are 1.2Ohm (typical) and LDO dropout voltage in TPS61098…

  • TPS61098: Mode and Iq

    TI Thinks Resolved
    Part Number: TPS61098 Hello Expert, I have some questions. 1. Is the difference between ACTIVE MODE and LOW POWER MODE just the difference of turning off the internal LDO/load switch (Vsub) and keep on boost? 2. Is there any difference between…
