DC/DC regulator

Timothy D. Swieter

I swear I asked this question in this thread before, but my searches on search.parallax.com are not returning what I am looking for, so here goes again.


I am looking for advice on DC/DC regulators.· Input to the regulator circuit would be 12 to 24V DC.· Output would be 5V or maybe 3.3V too.· One IC I found is this:· http://www.linear.com/pc/productDetail.jsp?navId=H0,C1,C1003,C1042,P36533.

As I said it seems like I ask this before and someone volunteered an easier IC.· I wanted to say it was from National or TI but I am not having any luck finding the reference.

Thank you.

TI, PT5100-series regulators.· They have the 7800-series footprint.

Hi Timothy,

What would be the maximum amount of current do you expect your circuit to use? For most power supply applications any of the 78XX and/or 79XX series voltage regulators are hard to beat. They're very simple to use, cheap, readily available and there are many thousands of different circuits on the web.

The regulator in your link is for switching power supplies, which are more efficient than the 78/79XX series regulators, but the 78/79s are much simpler.

Here's a link that shows a basic power supply using the 78XX series regulator.

The Nat Semi Simple Switchers are very easy to use, and they have on-line design software for them.

Thank you for the feedback so far. None of the suggestions so far are ringing any bells in my memory. I do however like the PT5100 and Simple Switcher ideas and I will investigate those. I a glad I asked, otherwise I may have over looked the options suggested in pursuit of other products that are coming up in my research.

I also corrected by first post because I meant 12 to 24V DC as an input.

There are a couple applications in mind, but nothing solid to calculate numbers on just yet. One app is a small Propeller project with power needed mainly for ICs/display. I wanted to avoid linear regulators and look at DC/DC switching regulators for effeciency as well as to learn more about them. Another application deals with a product design, but those concepts aren't exactly ready to decide on linear vs switching. I just want to be more educated to make the right decision.

If anyone has any other products to look at, let me know.
