EV3318-C-00A 2.7-5.5V Step-Up White LED Driver Evaluation Board WLCSP-12

The MPS EV3318-C-00A is an evaluation board built around the MP3318 for bench characterisation of the device in its intended topology. It operates from a 2.7 V to 5.5 V input and switches at 1 MHz. The board carries the device in its WLCSP-12 package.

The EV3318-C-00A is an evaluation board for the MP3318, a white LED step-up driver with a 2.7V to 5.5V input voltage range and 3-channel current sinks.

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.
