EVQ2483-Q-00A 4.5-55V Programmable Frequency White LED Driver Evaluation Board AEC-Q100 QFN10
The MPS EVQ2483-Q-00A is an evaluation board built around the MPQ2483 for bench characterisation of the device in its intended topology. It operates from a 4.5 V to 55 V input. The board carries the device in its QFN10 package.
The MPQ2483 is a 55V, white LED driver suitable for either step-down or inverting step-up/down 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.
