Hi guys, I need some advice on Boost-Buck DC-DC Converters.
Can someone please have a look at this 'Boost-Buck Adjustable Converter' on this web page (eBay): **broken link removed**
Would this circuit provide a set voltage output (assuming via the VR at the V-OUT) whether the input voltage (at V-IN) is Lower or Higher than the required output voltage? For example, let's just say I wanted 12.5 volts at the output... Would I get 12.5 volts at the output even if the Input was, say, 11.5 volts or even 14 volts?
What I have is a DC voltage that can be anywhere between 11.50 and 14.00 volts, but I want to regulate this to a set voltage of 12.5 volts (or thereabouts), DC, current up to 1 amp but possibly a bit higher. Found this circuit on eBay... Product Description gives me the impression that it may do the job for me quite nicely, but after researching Boost-Buck converters on Google, I am really lost now due to how complex buck and boost converters are (separately, let alone combined into one single package!). But maybe this one being "automatic" it's simple to use?
Unfortunately, the seller says there is no documentation available due to it being "DIY", so I can only go off the text on their eBay ad.
Do I need to apply any clocking or switching to this particular one, or do I simply provide an input voltage and then adjust the VR?
Thanks in advance.
