  • Re: TPS40195 ILIM

    Resolved
    Hi Andreas, Your observations are correct. R6 does appear to be a function of Q1 in SwitcherPro. As per data sheet, it should be a function of the low side MOSFET. I will follow-up with the system engineer for this part and request an enhancement…

  • What is the minimum load required for the TPS54550

    Other Parts Discussed in Thread: TPS54550 In reviewing the data sheet of the TPS54550 device it would appear the load current could go to 0 A with the regulation being within 0.1% with a Vin of 12V. Yet when I run SwitcherPro it doesn't allow me to set…
