EV3371-R-00A 3-30V Synchronous Boost WLED Driver Evaluation Board QFN-24
The MPS EV3371-R-00A is an evaluation board built around the MP3371 for bench characterisation of the device in its intended topology. It operates from a 3 V to 30 V input. The board carries the device in its QFN-24 package.
The EV3371-R-00A is an evaluation board designed for the MP3371, a synchronous boost converter with eight current channels designed to drive WLED arrays for LCD panels in tablets and notebook backlighting applications.

Evaluation Board
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.
