• RE: using LT3580  for genrating  –5V


    Thanks for the inputs.Everything  connected perfectly & rechecked the grounding also.Finally replaced the faulty LT3580 with new LT3580. Output is O.K now.Thanks for your support.

  • Problem with driving a circuit using boost converter(LT3580) from Li-ion Battery

    Hi All,

    I have a device that runs on 9V battery. It consumes about 100 mA @ 8.5 V. I am trying to replace 9V battery with rechargeable Li - ion battery (1 cell nominal 3.7 V). I have connected Li-ion battery to input of LT3580 (schematic attached). The…

  • RE: LT3580 EP range: reference and package


    thank you for the answer. Does it mean that the LT3580 doesn't exist in EP range ?


  • RE: LT8580 Frequency Foldback

    If this part uses the same control circuit as the LT8580, or LT3580, I would expect the same behavior.

  • LT8335 vs. LT3580

    In my design I need 2 supply rails +12V & -12V from a +5V. I will be using these supplies to power transceivers that are rated a max current drawn of 120mA\130mA. In order to give enough spare in the power ratings of the required solution I thought of…

  • RE: High Voltage Power Supply (2.5 KV+)

    This simulation is using the LT3580 designed using the suggestion schematic.  The current spikes on the inductor as the voltage ramps up exceeds 100A!!!  This is just to 350V without the charge pump multiplier.  What am I doing wrong?

  • Faied to output -15V using LT3580

    Hi everyone,

    It looks like that it doesn't let me to upload .asc simulation file, so I just take a snapshot, sorry about the inconvenient.

    So I was trying to output -15V from LT3580 with 15V input. Could anyone help me to check whether this design…

  • RE: Component recommendation to generate +100 V and can drive up to 20 mA

    Since you are experienced with the LT3580, you can consider the LT8331 which has an 140V internal switch.

    Thanks to the high voltage switch, the voltage multiplier is not needed.

    The circuits shown below are from the LT8331 datasheet and the LT8331 design…

  • RE: LT3582 operation in single output mode(Positive output).

    Hi, The LT3582 cannot be used for your application, as its switch current is too low for your needs.

    Also. the specifications you have provided cannot be met with a boost converter since your output could be lower, or higher than the input.

    Your application…
