Hey everyone. I've been hiding this update for a while now so that I didn't get anyone too excited. But, now that they are due to arrive any day now, I figured I would make the announcement.
Over the last few weeks, I have been in contact with Gary at SurvivalLasers and DTR with regard to my new buck drivers that I have been working on for a few months. Ever since Clif closed down his shop, I figured it was time to update the board and make it a bit more effective for what we need them for! That means lower part count, more heatsinking space, higher efficiency, less ripple, and minimal to no input spike.
Specs:
Input Voltage: 1.2*Vin - 16V
Output Voltage: <1V - 9V
Output Current: 1.5A - 3A (varies slightly per board)
Ripple Current: <100mA
Input Spike Current: <100mA
Efficiency: 85-90%
Circuit Continuity: Isolated D- and D+.
Features:
- Thermal shutdown. Will protect your driver (and diode) in the event of driver overheating. Once it reaches the temperature threshold, it will shut down until the main IC drops to a sufficiently low temperature to restart again. However, if left on, it will decrease in temperature, turn on again, and then turn off again due to temperature increase. This will lead to a pulsed effect on the output. This indicates it needs some rest time.
- Soft-start. There is a 1ms soft-start built into the driver to prevent large inrush current spike.
- Open-circuit protection. No current will be drawn and no current will be outputted when the test load or diode is disconnected from the output. It will not damage the driver whatsoever leaving it like this for any amount of time.
- 3mm potentiometer for allowing smooth control over the current output.
These will be available in Gary's shop at SurvivalLaser.com in the coming days! I shipped them out to him on Wednesday, so I bet they will be in stock by early next week. Expect a price of $20 with the standard LPF discount.
Rectangular versions of this board will probably be a few weeks, but they will be available in DTRs shop once they are finished.
Happy lasing!
(I am going to write up a PDF this weekend for proper usage and I will post it here.)
BlitzBuck V4
Note: You'll notice one of them has some solder on it. That was one of my test boards. It works perfectly, just has some extra solder on it! No worries!
