LED circuit calculator for flyback topology. (Excel sheet)
The excel coil and sense resistor calculation sheet.
This tool is targeting fly back boost topology.
This is a tool to balance your LED-driver circuit, and to estimate component values. The tool describes (a bit simplified) how the wave from of the current over the diodes will look like for different number of diodes, type of coil and current sensing.
Play with this tool and you will get a sense how to design your specific circuit.
A remark:
In your application especially for fly back topology you should put a relatively large capacitor on the output parallel with the LEDs. This tool does not include that optimization of that capacitor!
