Other Parts Discussed in Thread: TPS92620-Q1, , TPS92629-Q1
Hi all,
I need a constant current controller for an LED lighting application The specs as it stands now:
48V input
32-48V output (48 preferred, but that seems hard to find)
Software adjustable current - This is a lighting system for a vision system with a very fast exposure time, so I can't use PWM dimming, as it could cause uneven exposure between frames, but I do want software to be able to set the current through the LED's to adjust brightness
75 mA max output or higher
2 independent channels, but I don't mind using 2 parts if necessary.
I've been looking around for a day or so and am really struggling to find something that meets my needs. The part I mentioned in the title, for example, looks like it has a fixed current set by an external resistor - Does TI make a part that is similar, but with software-adjustable current?
