A switching regulator instead of linear for Arduino

Linear regulators in Arduino get hot. I have made some Atmel/Arduino boards with switching regulator. I can take hundreds of milliamps from it and it wont get hot even though I use 24V input.
Of course this is no secret, so a model with a switching regulator could be usefull for those who build larger systems and do not design their own PCBs.

This is one example, and there are others. They are a bit like old 7805 devices.

Hi,
Here's an Arduino UNO derivative with a 2 amp switching regulator built onboard:

You can see the switching regulator chip and inductor on the lower left.

OK. Good to see that someone has done it.

Have you seen the device I linked. It is perhaps a little higher but easy to use. And only one component is needed.

Those RECOM switching regulators from DigiKey are damn near bulletproof !! I have used a few of them in projects - just install it and forget it !!

Yes. They are reliable. I am using those or similar in a commercial product. I have burnt one those when I fed 5V into the output.

Yes I've seen those; the inductors/capacitor are inside the module I believe.

Easy to use but only 0.5 Amps. Not that much better than Arduino linear regulator except at higher input voltages like 12V+

2 Amps is 4 times as much and works particularly well for multiple servos.

terryking228. Have you any Due with a switching regulator. I have one regular one and it’s regulator is perhaps over heating. Or it does not like the USB chargers I am using. There is LCD and a couple of other modules on it.
If the price right I might buy one someday.

Have you any Due with a switching regulator.

The regular Due should have a switching regulator by default...

Which regulator is it?

Thanks. I didn't know. I have to look.

I looked at the DUE schema and it really has one switching regulator at Vin. But it makes +5V. The rest is made with linear regulators.

I've been using the OKI-78SR-5
https://www.digikey.com/products/en?keywords=OKI-78SR-5

I like that it can take up to 36VDC. A 24V battery can have a charging voltage of 30VDC so the OKI allows some margin. It has an MP2467 from MPS which works so well the undersized inductor on the OKI even works, someday I want to build a board with it that has a 3.5A inductor and find out if it can do the 2.5A to keep a Raspberry Pi3 B+ happy (The OKI also powers a Pi Zero very well).
