    EV2174C-G-00A 2.7-5.5V, 4A Synchronous Step-Down Switcher Evaluation Board QFN12

    The MPS EV2174C-G-00A is an evaluation board built around the MP2174C for bench characterisation of the device in its intended topology. It operates from a 2.7 V to 5.5 V input, is rated for 4 A and switches at 1.1 MHz. The board carries the device in its QFN12 package.

    The EV2174C-G-00A is used for demonstrating the performance of MPS's MP2174C, a low voltage high switching frequency step-down switcher with built in 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.
