Hello, We're going to design a dimmable led driver. This circuit needs to be isolated(flyback topology) and operates at 30 to 50 watts. The LED chipset is COB 50W(28v-32v and max current 1500ma) but we can change the chipset to other models. Additionally, the circuit's efficiency must be greater than 85% and its power factor must be greater than 0.9 in the power range of 30w-50w. Is it possible to implement this circuit using the LM3447 while keeping in mind top-quality elements(low ESR for capacitors, low leakage for transformer, low Rds for MOSFETs)? What do you suggest if not? do you have an application note for this circuit?
