| | I haven't done anything with switching regulators other than building my first with a TI TL494 PWM controller IC. I looked at Roman Black's designs (Thanks for that turn on) what elegant simplicity! I'm in awe. I am happy to contribute to a linear regulators page--I have several discrete opamp based designs for dual tracking supplies etc. I'd like to see more switching designs, to expand my own knowledge and raise my conciousness. I've peeked at National's online design software, but never took the time to try anything. | | I haven't done anything with switching regulators other than building my first with a TI TL494 PWM controller IC.

| − | I have a little project that requires +3V, +5V, and +&- 15V. I'm trying out TI's 2W DC/DC converters: DCP020515, DCP020503, and TPS5430 Step Down Converter for that application, but it's on a back burner for a while. If anyone has any experience with these I'd like to hear about it. | + | I have a little project that requires 3V, 5V, and |

| − | I've just been going through the documents I've downloaded and the samples I have on hand from Texas Instruments. The more I think about it, the more a page for switching regulators makes sense. I think it should be broken into different manufacturers offerings with a cross reference at the beginning or the end--assuming there is crossing. There may be more differences than duplications--I don't know, so that is something to be researched. This should be presented to the whole community for feedback.

| − | I responded to your question on [[User talk:DavidCary]].
| |
| − | I responded there, rather than here, because the last time I put half of a conversation in one place, and the other half in another place, I only confused myself :-).

| − | == editing line drawings ==
| |
| − | | |
| − | For editing general line drawings,
| |
| − | the best editor I've found is "inkscape".
| |
| − | Download it for free ( http://inkscape.org/ ).
| |
| − | | |
| − | Some people use inkscape even for sketching schematics.
| |
| − | Other people prefer a specialized [[techniques#software_design_tools | schematic editor]].
| |
| − | | |
| − | Congratulations, you've already posted more images to Open Circuits than I have :-).

| − | == writing on wiki ==
| |
| − | | |
| − | Some of my favorite pages about writing on wiki are:
| |
| − | | |
| − | * [http://communitywiki.org/SentenceToPageToSectionToWiki "sentence to page to section to wiki"]
| |
| − | * [http://communitywiki.org/BigBucketsFirstExplanation "big buckets first" explanation]
| |
| − | * [http://communitywiki.org/PlainTalk Plain Talk]
| |
| − | | |
| − | I'm dropping little snippets of information here, even though I plan to separate them out into another page someday.
| |
| − | The "sentence to page" and the "big buckets first" essays should explain why I do this, rather than creating a fresh page now and placing 2 snippets of information into it.

You removed information that others spent time and thought composing and sharing with the community. If you did this by accident, you owe it to yourself and everyone else (not only on this wiki, but on every wiki) to learn how to use the tools properly, so you don't damage things.

| − | Someone seems to have nothing better to do than F with stuff they shouldn't. This is the second time in as many weeks that someone stuffed a whole bunch of links at the top of this page and deleted most of the text towards the bottom. This is very poor behavior and being it's the second time, it feels malicious, no benefit of the doubt about it.
