2.1A 25V boost converter
input 10-18V output 2.1A at about 25V. This is my first revision, it has some issues. note all of the extra caps soldered onto it, the inductor current is around 11 amps and that causes some issues with stability. if input power is not very high quality the converter goes into a low frequency (audible) mode and causes rapid heating of the mosfet. But it is able to drive my 50 Watt bridgelux 4500 lm LED
