Can anyone help me understand lm3409hc to choose these values?
Once you have your nominal switching frequency, you can then choose the inductor ripple current. Here is the schematic: I have completed a number of projects here.

The latest version of the board looks like this: It means that with current availability, you can put 8 drivers with MCP or 4 drivers with MCP on a single i2c bus. I aim to drive a single LED with a maximum constant current of 2. Thus you need to calculate based on the LED’s you plan to in order to not over stress them.

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. I will do my best to complete the project perfectly.
There were really only a couple of options for a DAC choice.
