i would like to incorporate a similarly simple step up converter onto my circuit.
, if i wanted to allow for more current, how might i go about that?
Could anyone be kind enough to provide some information for how these are constructed and with which parts?
Better to pay a bit more and know the complete details of what you are getting. See Pololu's collection of boost converters. Plus, they support their products.
A reliable distributor will give you the specs and sometimes a link to the manufacturer's datasheet. You don't always get a link to the schematic or components used, but you should get complete specifications. ...If you buy the cheapest thing you can find on eBay or Alibaba, etc., you're on your own and you take your chances.
I think i was just very impressed by the limited number of components of the original converter i posted and though 'hey i could totally buy those comonents and put them directly on my PCB" - i just wondered whether anyone might know exactly what they were and how they were connected together.
This is one of those things that looks simple in the textbook but the actual implementation is much more complex.If you saw a diagram of a jet engine in a book, do you think you could build one from parts?
I suspect the regulation performance is very limited, the lack of input capacitor will make it very noisyelectrically, and not knowing its basic performance means you're going to have to measure them to besure its suitable for a particular use. The lack of a separate feedback pin means it can only be a fixedoutput voltage, not programmable.A datasheet would be good, its probably perfectly good for lots of non-critical applications, cheap andeasy to hand solder for an SMT component too. I suspect its designed for phone-chargers.
I don't suppose anyone would be able to 'fill in the blanks' so that i could get a 5v output from this thing could they?
Sure it is. All you need is a compressor, combustor and turbine.You can build one at home with a car turbocharger providing the compressor and turbine. A coffee can can be used as the combustor. Of course that homemade jet engine is 100% efficient at turning fuel into noise and produces no useful thrust.
Well, you can always just just buy one of these and reverse engineer it. Pretty simple stuff. Set it to 5 volts and measure the pot. You'll find the output noise in these elCheap-o Chinese converters is pretty crappy. They're okay for chargers and LED's which is the target market.Don't expect much from them and you won't be disappointed.
All in all as long as the efficiency is fair and it can power my arduino mini reliably then i am ok. im not building cutting edge tech here.
