EV3398E-F-00A 4.5-33V strings WLED Controller With 80V Return Evaluation Board TSSOP-16

The MPS EV3398E-F-00A is an evaluation board built around the MP3398E for bench characterisation of the device in its intended topology. It operates from a 4.5 V to 33 V input. The board carries the device in its TSSOP-16 package.

The MP3398E is a step-up controller with four current channels designed to drive 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.
