I know what you mean ..... LOL !
What chip is that? Looks very simple... Do you use the toner transfer method from label backing for an etching mask?
My driver used to be so crowded in the early version, that capacitors had to stand on other capacitors... :angel:
Here is a photo of the upper side of an older (v2 - now i'm at v4) driver, there is a huge coil and a schottky on the other side...
Problem was, in this version, there was no room for the output caps next to the diode pins - i had to solder a "capacitor-sculpture" ON TOP of the diode pins AFTER it was soldered to the driver... :yabbem:
I managed to rearrange it in later versions, so it has more room now around diode pins... No more capacitor sculptures.. :crackup:
This is 13x9mm, i put it next to a complex TEC driver IC for the photo, just for the size comparison...
The two resistors in the bottom right corner have jumpers next to them, for higher current selection...
EDIT: Ahem, this pic is not very flattering, i need to take a new one of the latest version. :angel:
