    EVQ4576-QB-00A 5-60V, 0.6A Synchronous Buck Converter Evaluation Board QFN-12

    The MPS EVQ4576-QB-00A is an evaluation board built around the MPQ4576 for bench characterisation of the device in its intended topology. It operates from a 5 V to 60 V input and is rated for 0.6 A. The board carries the device in its QFN-12 package.

    The EVQ4576-QB-00A is an evaluation board designed to demonstrate the capabilities of the MPQ4576/MPQ4576-AEC1, a fully integrated, fixed-frequency, synchronous step-down 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.
