Hey guys! I have been looking at low cost red builds lately, and the ML101U29-25 diodes have come up ($3 per diode)
These are rated at 400mw and a perfect current for these is 350ma. Coincidentally, the AMC7135 chip puts out 350ma! In a very compact package!
Anyways, the forward voltage stated on the ML101U29-25 datasheet is 2.35 - 3 volts (typ - max) so generally will have about 2.5 fV.
I want to use one cell. Maybe a 16340 or an 18650 etc. So input voltage will be 3.9 - 4.2 volts.
I have looked and looked. So i have two questions.
The Vf of the ML101U29-25 is slightly higher than the other mitsu diodes. Will it still work with a single cell?
What is the pin-arrangement for the AMC7135? The three pins from left to right and the GND pin on top?
Also, if i want to make a very compact red driver out of these chips, all i would need is the chip and a diode for reverse polarity protection? Feel free to shoot me if i am being really stupid with anything i say.
Any help with this would be greatly appreciated!
Thanks
