Hello. I'm trying to design a AC to DC LED driver with PWM dimming. I have a design that I can use with the LM3406HV but I would like to design something that I can wire up 110V AC mains line. With the LM3406HV I need a DC power supply. I was thinking about using a switching power supply but if I can make one that's all-in-one then it will be better. I need 8 drivers with 42V DC at 850mA output. I'm planning on using the PWM for dimming. I don't think I need all the power that I'm planning on having but it's nice to have the power just in case I need it. If anyone is wondering, I'm trying to build a LED lighting system for a reef aquarium. I know there is a lot of tutorials out there for this already but I thought I would ask here and see what the opinions are. Also, I could buy a lighting system but I like building system, so that's why I would to design something and build it myself.
