EV3391EY-00A 10-28V String White LED Driver Evaluation Board
The MPS EV3391EY-00A is an evaluation board built around the MP3391EY for bench characterisation of the device in its intended topology. It operates from a 10 V to 28 V input.
The EV3391EY-00A is an evaluation board for the MP3391EY, a step-up converter designed for large liquid-crystal displays that employ an array of LEDs as the light source.

Design Notes
- The board ships in a default configuration; check the jumper and resistor options against the user guide before applying power.
- Respect the input terminal rating — most faults on evaluation boards come from an supply above the marked limit.
- Test points on the switching node and output are for a short-ground probe, not for a long oscilloscope lead.
- Where a GUI is supported, connect the dongle before power-up so the device enumerates on the I²C bus.
