EVQ2489-Q-00A 8-36V Step-Down White LED Driver Evaluation Board QFN6

The MPS EVQ2489-Q-00A is an evaluation board built around the MPQ2489DQ for bench characterisation of the device in its intended topology. It operates from a 8 V to 36 V input. The board carries the device in its QFN6 package.

The EVQ2489-Q-00A is an evaluation board for the MPQ2489DQ, a step-down converter designed in continuous current mode for driving the high brightness light emitting diodes (LEDs) from wide input voltage 8V-36V.

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.
