LM2576 - Worth to download the updated datasheet

atferrari · Nov 18, 2014

Datasheet revised on 2013 by TI.

Wonder if it will work with Win 8.1...

"To further simplify the buck regulator design procedure, National Semiconductor is making available computer design software to be used with the SIMPLE SWITCHER line of switching regulators. Switchers Made Simple(Version 3.3) is available on a (3 1⁄2") diskette for IBM compatible computers from a National Semiconductor sales office in your area."

Does anyone still have a computer with a 3.5" floppy disk drive?

Not for a few years

The Motorola data sheet mentions "National Semiconductor" twice.
The Micrel data sheet does not mention "National".
The TI data sheet for the (HV) version only mentions that the National data sheet was changed to a TI data sheet.
The TI data sheet mentions that the National data sheet was changed to a TI data sheet.

You must be looking at a old data sheet.

Sounds like a bank. LOL

In other words, go here.

Look at page 25;
"Changed layout of National Data Sheet to TI format"
The original date for that data sheet is 1999.
The last revision for the software came out in 2009.
Its all old stuff.
Try it if you want!

As long as we are talking about companies and computer stuff that does not exist now:
Does anyone have the original LM555 data sheet?

Found the software for the LM555

Yup. I need that for the backup copy of the OS. My desktop PC is still running Win98!

4pyros · Nov 19, 2014

I still have a few win98 machines and original copy's of the OS on 31/2 disks.

Does any one have a spice model for the LM2576?

atferrari · Nov 21, 2014

After four days of searching in very creative ways I found nothing. In my case I gave up.

In four days you could make a spice model of this:

atferrari · Nov 21, 2014

Yes, I could, but I am not Ron Simpson. The necessary things he knows, I ignore them.

kinarfi · Nov 21, 2014

No I couldn't, I don't have the experience, or knowledge, wish I did.
