About single output 20A in LTpowerCAD of LTM4646

Hello

I would like to use it with a single output / 20A of LTM4646.
I want to design using LTPowerCAD, but I couldn't put the channels together in LTM4646.
Since I was able to combine channels with LTM4668A, I think that LTM4646 does not support it.

If you have data that supports single output with LTM4646, I would be grateful if you could share it.

Best Regards,
Knj

Hi Knj,

Snip below is from the datasheet of LTM4646 on page 28. Is this what you're looking for?

  • Hello

    thank you for your reply.
    I would like to simulate a circuit that can flow 20A with one output with LTPowerCAD.
    If you have a confirmation method or data that can output 20A per output with LTPowerCAD, please share it.

    I would be grateful if you could reply.

    Best Regards,

    Can you confirm if I'm understanding you correctly. You want to use only one phase, and it should be 20A, is that correct?

  • Hi Knj,

    I believe LTpowerCAD can support that. Please open LTpowerCAD and search for LTM4646. Enter your specifications and make sure the max paralleled option is set to 2.

  • Thank you for your reply.

    The data you received seems to have two devices connected in parallel, but is it a collection of two outputs from one device?

    Taking LTM4668A as an example, by setting the output to two, the output of one device is combined.

    However, if you do the same with LTM4646, you will get an error.

    Please let me know if there is a way to combine the outputs of one device with LTM4646.

    I would be grateful if you could reply.
