I am looking at the NSI45060 device and would like to know what the formula is for calculating Radj. Where can I purchase an EVM for this product?

For Radj the figure on the datasheet estimates what resistance is needed to adjust for a chosen current.The adjustment depends on various conditions such as the board thickness, copper thickness, footprint area, and ambient temperature.

You should breadboard or build a prototype and test it to find the precise adjustment.

We have an evaluation board (CCRGEVB) available at our website. Please refer to our evaluation board (CCRGEVB) Constant Current Regulator Array Evaluation Board.
