EVQ4425B-QB-00A 4-36V, 1.5A Step-Down LED Driver Evaluation Board QFN-13
The MPS EVQ4425B-QB-00A is an evaluation board built around the MPQ4425B for bench characterisation of the device in its intended topology. It operates from a 4 V to 36 V input, is rated for 1.5 A and switches at 400 kHz. The board carries the device in its QFN-13 package.
The EVQ4425B-QB-00A is an evaluation board for the MPQ4425B, a high-efficiency, synchronous, rectified, step-down, switch-mode LED driver with integrated internal power high- side and low-side MOSFETs (HS-FET and LS- FET, respectively).

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.
