    EV3331-C-00A 2.7-5.5V, 2A Flash LED Driver With I2C Interface Evaluation Board WLCSP9

    The MPS EV3331-C-00A is an evaluation board built around the MP3331 for bench characterisation of the device in its intended topology. It operates from a 2.7 V to 5.5 V input and is rated for 2 A. The board carries the device in its WLCSP9 package.

    The MP3331 is a single 2A flash LED driver with very compact package, high efficiency for high- resolution camera phones to improve image and video quality in low light environment.

    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.
