    EVQ4480-V-00A 4.2-36V, 6A Step-Down Converter Evaluation Board QFN25

    The MPS EVQ4480-V-00A is an evaluation board built around the MPQ4480 for bench characterisation of the device in its intended topology. It operates from a 4.2 V to 36 V input, is rated for 6 A and switches at 2.1 MHz. The board carries the device in its QFN25 package.

    The EVQ4480-V-00A Evaluation Board is designed to demonstrate the capabilities of MPS' MPQ4480, which is a high-frequency, synchronous rectified, step-down, switch-mode converter.

    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.
