• LTC3803 loop compensation

    Is there some indication on how the feedback loop on the LTC3803 parts should be done? at least some starting point.
    The datasheet says that an RC series has to be connected to ITH/Run but I have never seen a compensation network between the output and…

  • LTC3803 soft start issue

    Hi ADI Experts

    I am using LTC3803 for POE at application. but I have some inrush current issue that needs to be reduced.

    since the SS is internally controlled by LTC3803, May I know if it is possible to build a external SS circuit on Ith pin?

    Does ADI…

  • LTC3803 isolated DC/DC

    I designed PoE power supply with using LTC3803, and it's work fine in non-isolated variant, but  i have problems with isolated variant. 

    Schematic of isolated variant:


    It doesn't work the way I want it to. By changing resistors R41 and R43, I cannot…

  • LTC3803 Flyback controller Overvoltage

    How does the LTC3803 Flyback controller prevent the output from exceeding the desired output when there is no minimum load?

  • Will the LTC3803-3 work as a "Dual Output Wide Input Range Converter"?

    The datasheet for the LTC3803-5 has a "Dual Output Wide Input Range Converter" on the front page. Would this circuit work on the LTC3803-3. I need a 3V@150mA output and a 12V@10mA output. I don't see such a circuit on the LTC3803-3.

    Thank…

  • isolated DC/DC recommendation

    Hi 

    I am looking for a isolated DC/DC converter 

    May I have your suggestion for my system

    the spec is as below

    -------------------

    Input Voltage: 41V ~ 60V

    output voltage/ampere : 19V / 2.63A ( 50W )

    current consumption @ NO Load <10mA

    -------------…

  • RE: LTC3779 use in non-synchronous buck-boost converter

    Hi 

    For Questions 2 

    it is possible to do so however it would be complex specially if you would target a fully isolated system 

    Mind looking at these controller as alternates ?

  • RE: LT3420 as HV power supply.

    Hi Victor, thanks for the response.   I’ve mostly just started the design, so specs are a bit fluid at the moment.

    For the APD, I’ll need fairly low ripple… I’m thinking less than 100mV, but I’m not really sure.  I’ve been looking at a different flyback…
