TINA/Spice/LM5069: LM5069

Part Number: LM5069
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

Dear All;

I am using LM5069 in a design. LM5069 has two datasheet as 'Revised May 2013' and 'Revised November 2016'. In datasheet versions  power limit calculations are different from each other. When I calculate power limit with 2 datasheets, I take different results.

  Revised May 2013

    Revised Novemeber 2016

Could you give me some detail about how can calculate power limit, fault timer and other parameters? Which datasheet is give correct results?

I hope you can provide information.

    Hi,

    Welcome to e2e! It's always best to go with the latest revision of the datasheet. In this case, go with the datasheet revised in Nov. 2016.

    Also,  I'm not sure if you're aware of our easy-to-use calculator tools for hotswap controllers. I would highly recommend to use this when designing with the LM5069. This will help review and troubleshoot your design, and would greatly speed up the back-forth communication of questions we would have for information needed for the review (such as total output cap including anything connected downstream from the output node, which may not be shown on a partial schematic).

    You can find it by going to www.ti.com/hotswap ==> click on “Tools & software” ==> then click on “Hot Swap design calculator tools”

    For help on filling out the excel spreadsheet, we have video tutorials. They explain how to enter the correct values cell by cell. The videos are at www.ti.com/hotswap ==> Click on “Support & Training” tab.

    I hope this helps :-)

    Best Regards,

    Aramis P. Alvarez
