Do any of you know of an adjustable switching constant current source driver that can be used to power the Bridgelux BXRA-C8000 LED array?
Typical current = 2.8A
Typical forward voltage = 30.4V
Current range = 1.5-3.75A (5A pulsed)
Forward voltage range = 27-34V
The driver needs to have PWM dimming and an external input for triggering/pulsing.
Luckily I have the luxury of selecting the power source later, so the driver could be DC-DC buck, boost or even 120VAC input (it will be in a vehicle application with large sine wave inverter.) DC power source could be the vehicle's battery or an intermediate regulated power supply at upwards of 48VDC.
I spent a good deal of time searching for this but I couldn't find anything commercially available that would switch on fast enough.
The LED will essentially function as a precision strobe, needing to turn on as fast as possible (<1ms) and turn back off after less than 10ms.
I have not had much experience with LED power electronics but am more than willing to learn. If there isn't anything like this on the market, what general topology would you suggest I look into for building my own.
Thank you very much for the help.
P.S. Bonus points if the driver can run multiple BXRA-C8000s
