    EV8774H-Q-00A 3-18V, 12A Step-Down Converter Evaluation Board QFN-16

    The MPS EV8774H-Q-00A is an evaluation board built around the MP8774H for bench characterisation of the device in its intended topology. It operates from a 3 V to 18 V input, is rated for 12 A and switches at 1400 kHz. The board carries the device in its QFN-16 package.

    The EV8774H-Q-00A Evaluation Board is designed to demonstrate the capabilities of MPS' MP8774H, a fully-integrated high- frequency, synchronous rectified, step-down, switch-mode converter with internal power MOSFETs.

    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.
