  • LTM4653

    Dear Analog/LT team, I'm in dire need of a little help.

    I've read the data sheet of the LTM4653 over and over again and I am still not sure, why this is happening exactly:

     

    Under some strange conditions the LTM just bursts in flames. My input…

  • Can LTM4653 be used in Constant Current mode?

    Hi,

    I'm interested is there a way to use LTM4653 in constant curren mode?  would need to convert unregulated 30-50VDC  to current regulated  0..4A with Vout Max 5V.

    LTM4653 seems to be ideal except it has no current limit  or CC regulation pin. Wandering…

  • Web page for LTM4653 has a photo of a Demo Circui 2327A board. I am guessing that the bd is not available for sale, but are the design files for the bd available?

  • LTM4653 - EXTVCC for 3.3V output?

    I'm using the LTM4653 for 28V in, 3.3V out.

    According to the datasheet, for Vout >= 4V, EXTVCC should be powered from Vout (through a resistor R_EXTVCC).  Is there any reason EXTVCC can't be tied directly to Vout when Vout = 3.3V?  Since EXTVCC…

  • Switch synchronising of multiple LTM4653 devices

    Hi all,

    I am currently in the process of designing a board that's main function is as a power supply. We have 48V coming in and require 4 individual, 26V, 3A (max) outputs. We have settled on using 4 LTM4653 step down converters with a switch frequency…

  • RE: LTM4653 - optimal thermal PCB layout and thermal theda values

    The evaluation board is a good starting point.  It is optimized including EMI and thermals performance. Thermal testing on your actual board design is recommended.
