No they are step down only. Linear regulators work by more or less by "dropping" excess voltage... which for practical intents and purposes means converting excess voltage into heat.Is linear regulator like 7815 can boost voltage from 12V to 15V ?
How much current do you need ?Hi , is there any regulator IC gives output voltage 13V to 16Vdc for input voltage of 12Vdc .
I made a jouletheif type circuit with 2.2uH kind of inductors, really tuned it to the margin.An MC34063A will do the trick. These are switching regulators, so your design problem does not stop with finding the IC. You need to carefully select an inductor and find a source of low ESR capacitors. You need to follow the calculations in the datasheet to avoid nasty surprises in the final product. Last point is:
"Only a fool would build a switch mode power supply on a bradboard."
At least nobody here would ever do such a thing.
Hi , these power supply is for mosfet driver supply so they require very low current something around microamps(uA).How much current do you need ?
