The schematic is basically the reference design plus a few small additions for dividing 5V into what the driver expects for analog dimming useful for arduino and similar other controllers. What does the larger PFET help with? Quite a few changes have gone in. Here is the schematic: The product detailed below complies with the specifications published by RS Components.

It means that with current availability, you can put 8 drivers with MCP or 4 drivers with MCP on a single i2c bus.

My intent is to understand how to calculate the values of the components needed for my specific application. Save to parts list Save to parts list. Hi, I have been reading through the whole thread on Reef Central but I keep getting a little lost with all the ramblings from other peolpe. Your project is really interesting to me and i can do your project correctly. In your case the input voltage 42V and output load LED’s are fixed. Email Required, but never shown. The luminous flux of an LED is mostly linear, but at a certain point some of the current just leads to heat.

Excellent, I will keep checking back for an updated version. What does all this mean? I can provide you with service from schematic entry to PCB Layout. And have worked on LM before. The two are basically the same DAC, but one has external addressing, while the other has external reference voltage.

Flux and thin solder make life easy when you deal with SMD components! For additional understanding see section 2. I have completed a number of projects here. Hi, I read your project description.
So, the optimum value of the inductor needs to be optimized.
