How much are you asking for these drivers? Since there is no pot, I assume it has a fixed resistor for current output. Is there a shipping cost and do you have any scope pictures of the output? Does it have thermal shutdown? There are so many questions.
Looks pretty basic driver, not sure how the output will look because the IC is defaced.
For the 1A
4 Caps
3 Resistors
1 Shottky
1 Inductor
IC
Hmm... good work making a driver thatung but gotta list tons of details and proof of stability before offering to sale brother.. If you start killing people's diodes they will be pretty upset. You should send some to guys who have knowledge and scopes for testing as well...

Seems like everyone who offers a buck driver defaces the IC, as if it couldn't be reproduced without that specific IC's part number.
i thing at 2.4A the IC will blow up just the way its all soldered !!
Yes I know =/ I hope to open source one soon.
Also, goodluck again thatung let me know if you wish to have me test any of your drivers. I am in the process of testing my own as well!
I understand heat sinking those IC's can allow higher current, but I'm wondering if the plastic case were shaved down so very little of it remains between the top, and the IC dye itself, whether that might increase the maximum amount of current due to better heat sinking, if less plastic between the silicon and the heat sink? Perhaps this isn't enough of a factor for higher current and other design properties limits it more?
thanh tung if you ever decided to sell these put them at around $25 each.
if you could put in the potential meter to adjust the current lot's of people will buy it.
i could communicate in Vietnamese as well. just Private message me.
I might ask you to mass produce laser host as well!!.( people usually pay $80- $180 for one host).
Shipping is $20 from Viet Nam to overseas?.
