I am looking for some LED driver capable of 8V / 10A output (constant current). Vin is 14-28 (24 nom). Current is set by PWM. Is there any reference design avalibale for this application?
My current idea is to use buck (f.ex. LM61495) with opamp in the feedback loop for setting the current based on voltage at current sense resistor (and also by Vref set by PWM). Current plan is to set the crossover frequency to about 10% of Fsw, alre there any other general recommendations, or some reference design for this application?
Application is pretty much space contrained, thats why DCDC with internal switch was chosen.
