• 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.

    The converter based on LTC3803 enters the pulse-skip mode.

    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 ?



  • 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…

  • RE: LTC3803 loop compensation


    Please consider LTC3803 datasheet, ITH pin

    ITH/RUN (Pin 1): This pin performs two functions. It serves as the error amplifi er compensation point as well as the run/shutdown control input. Nominal voltage range is 0.7V to 1.9V. Forcing this pin…

  • 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…

  • +-5 from single +5

    can you suggest any way to produce +-5 from +5.
    I need it for one 4ch differential signal summer op-amp plus salen-key filter op-amp.

    Is there any DC/DC converter or something in ADI that doing this?

  • PSPICE file for LT1761ES5-5

    Therse is LTspice file present for this LT1761ES5-5 but it not compatible with TI-TINA simulator. 

    Please help me out by providing a SPICE file for this part so that I can import it to other tools as well.

  • RE: AD7091R-5 I2C


    So I spoke to the designer and I believe the model you provided in your thread above is accurate for SDA in that there are protection diodes in the SDA pad for when the device is to be a SPI part.   The problem is that POWER must be applied for…

  • LTC4089(-5) typical application

    In typical application, 1k resistor is connected between HVPR(pin 7) and OUT(pin 13).If high voltage is

    present, the HVPR goes low( near to GND) and opens external p-fet to drive high voltage (vbat+0.3V/5V)

    to OUT. At same time, ca 3...5 mA  are going…
