    EV4245-VE-00A 4-36V, 6A Buck-Boost Converter Evaluation Board QFN21

    The MPS EV4245-VE-00A is an evaluation board built around the MP4245 for bench characterisation of the device in its intended topology. It operates from a 4 V to 36 V input, is rated for 6 A and switches at 420 kHz. The board carries the device in its QFN21 package.

    The EV4245-VE-00A is an evaluation board for MP4245, a Buck-Boost converter with 4 integrated power switches.

    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.
