    EV2155-Q-00A 2-5.5V DC/DC Buck-Boost Converter Evaluation Board QFN-10

    The MPS EV2155-Q-00A is an evaluation board built around the MP2155 for bench characterisation of the device in its intended topology. It operates from a 2 V to 5.5 V input and switches at 1 MHz. The board carries the device in its QFN-10 package.

    The EV2155-Q-00A is an evaluation board designed to demonstrate the capabilities of the MP2155, a highly efficient, low quiescent current (IQ), buck-boost 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.
