I want to build a 12v to 14v converter with LM2577T-Adj but i found 12v to 16v scheme diagram, any one can help what part i should chance to...?
in this scheme to make 12v to 14v output...?
hi,
Reduce R1 [12k] to about 10.5K.
This is the Vsamp feedback to the switcher.
Look at the Vout formula [near the Vout terminal]
Vout = 1.23 * [1 + 10.5/1] = 1.23 * 11.5 = 14.14Vout.........OK?
Have you checked that the appliance designed to run from 14V won't run off 12V?
The chances are you're wasting your time as you don't need a switching regulator.
The chances are the device will work from 12V so a 14V supply is not required so building one would be a total waste of time.How would you step-up from 12V to 14V without some kind of switching power supply? ;-)

You probably can't.How would you step-up from 12V to 14V without some kind of switching power supply? ;-)
