EVQ3326-R-00A 4-16V, 50mA LED Driver Evaluation Board QFN-24
The MPS EVQ3326-R-00A is an evaluation board built around the MPQ3326 for bench characterisation of the device in its intended topology. It operates from a 4 V to 16 V input and is rated for 50 mA. The board carries the device in its QFN-24 package.
The EVQ3326-R-00A is an evaluation board designed for the MPQ3326, a 16-channel WLED driver that can operate from a wide 4V to 16V input voltage range.

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.
