EV3373-M-00A 9-40V Step Up WLED Controller Evaluation Board TSSOP28

The MPS EV3373-M-00A is an evaluation board built around the MP3373 for bench characterisation of the device in its intended topology. It operates from a 9 V to 40 V input. The board carries the device in its TSSOP28 package.

The MP3373 is a step-up controller with 8- channel external current sources designed for driving the WLED arrays for large size LCD panel backlighting applications.

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.
