STEVAL-ILL010V1: 350mA @ 20V Max, 8 ~ 30V in

Summary

This evaluation board is designed around an L6902D-based DC-DC converter with dimming interface. It board implements both of two well known dimming methods:

- Analog current control
- Average current control by PWM

While there is only a single dimming input connector on the board, it can be used for both dimming methods.
