  • LTC3621 undervoltage lockout

    Hi,

    I need some help with the LTC3621.

    1) Can I use a resistor divider connected to the RUN pin to program a higher undervoltage lockout voltage? Is there some hysteresis built into this pin?

    2) Can you point me to a document that explains the precautions…

  • General Spice Model for LTC3621, LTC8606 & LTC4417

    Hi Team,

    In our system we have couple of power regulators LTC3621 , LTC8606 from analog devices and TPS63070 from TI.

    We are performing analysis for ripple measurement, Load/line regulation independently in LTspice for ADI parts and TINA Tool for TI part…

  • LTC3621- Fixed 3.3V and adjustable regulator voltage drop

    Hi team,
    I have used the LTC3621IDCB-23.3#TRMPBF in my design and my input voltage is about 5v and configured to burst mode of operation.The feedback is bypassed to the SW pin(1) through the inductor.The output  voltage at SW pin(1) is 3V and INTVCC pin

  • RE: DC512B not working

    Zack,

    I tried putting the 10K pull down on the bottom FET, but this did not fix the issue.  This was on 2 new boards from the production run.  The battery was not connected, and the ICs worked for a couple seconds, and then stopped pulsing on the tgate…
