Hello Everyone!
Short of it - can anyone recommend some nice DC-DC switching available on the JLC Parts library?
https://jlcpcb.com/partsAlternatively maybe just from LCSC who have a larger range (but I'd have to pay extra to order them in) -
https://www.lcsc.com/I'm designing a board that needs to step down 30V to 15V and supply 2A Max. To be honest 1A is probably enough, if that gives a better choice I'll check the load to be certain.
I already built a prototype using the very common XL7015 (
datasheet here) converter that is common on lots of Chinese products and is about $0.5 from JLC PCB assembly service.
I've decided I'm not a big fan of this 'regulator' as the input has about 6mV noise but after the XL7015 it has increased to 12mV at @150KHz! That seems silly, and since this is an audio circuit I don't want extra noise if I can help it.
I've used the MP2359 (
datasheet here) in another project and it seems to work well with about 6mV noise (so not improving the input, but not making it worse) however that has a max input of 26V and this project needs to step down from 30V.
I can see the MP2565 (
datasheet here) that can handle 50V input but I don't know if it performs as well as the MP2359? I find it hard to compare the graphs between the documents.
There is also the MP9486 (
datasheet here) which can handle 100V input.
Maybe MP4462? (
datasheet here)Jesus there are so many!
