Hi.
I built a few of 445nm with v5, microboost.
But maximum current of v5 to 445nm is 1.2A and microboost is 1.1A.
So I am looking for high current driver.
I have my custom P60 heatsink already, so I can use round circuit board for LED.

Dealextreme's cheap 4x amc7135 driver can supply 1.4A, and 5x can 1.75A.
Input voltage of amc7135 ranges upto 6V-7V.
Vf of 445nm LD is over 4.2V.
And drop-out voltage of 1N54xx diode(3A) is 0.8V-0.9V.
I have question:
Can I build 1.4A/1.75A 445nm
with 4x/5x amc7135 driver
and 2 of serial Li-ion battery(8.4V)
and 3 of 1N54xx(ca. 2.5V drop) for voltage drop of batteries ??
I hope this will be possible.. Any comment welcome...:bowdown:
