Hi all,
I am looking at driving six to eight LEDs in series.
I have one power supply at 30VDC Pulse Width Modulated.
I want to create a constant current supply of up to 100mA to drive the LEDs.
I have looked at a number of IC's that can drive the LED's and also use a PWM for dimming, but these use a constant DC supply to drive them.
I expect the +28V to be used for the dimming.
Any ideas?
Regards
