Astral Driver - Boost, Buck, & Sepic

This is not a sale thread!
This is a discussion thread.


Hello all!

BACKGROUND STORY
So long story short, at first i kinda hesitant to design and manufacture a driver because i think people already satisfied with currently available driver,
But since i saw that there are so many monster diode emerged from the depth of a hell, and not to mention the declining stock of driver in market,
Then i decided to design a 12A buck driver with the dimension is only 15*10mm.
And due to addiction in designing things, i continue another one with boost topology capable of delivering 9A current with only 12.5*10mm.
After that, i think that i need to provide one to be used with low power diode,
So i design another one, a small one for small laser diode.

In the middle of design times i scaled down both the 12A and 9A to 6A, because i think it's not quite useful for now.
So the final are 6A for both buck and boost driver.

Estimated price for one unit when fully assembled: $29
  • Topology: Buck
  • Vin: 4.5 - 18V
  • Vout: 0.7 - 8V
  • Iout: 1.1 - 6A
  • Size: 15*10mm
  • Features:
    • Current regulated
    • Adjustable current
    • Soft start (1sec)
    • Delayed start (1.5sec+)
    • Thermal shutdown
    • PCB with 2oz (70um) copper, twice the copper thickness of usual PCB to maximize current and heat transfer.
    • Components mounted only on top side of PCB, allowing maximum contact from driver to heatsink, hence maximizing heat transfer from PCB to heatsink.
    • Thin PCB with lots of vias, maximizing heat transfer from top side to bottom side.
    • Component mounted and soldered using automated assembly machine, minimizing human error.

All of the driver above can be modded to be able to accept TTL/PWM

The driver is currently being manufactured, not sure when it will be finished
I only fabricate in small number for now
I hope these can balance the supply and demand of driver these day
Thanks for looking! :beer:
