    EVQ9843-L-00A 5-36V, 3A Low Quiescent Current Synchronous Step-Down Convertor Evaluation Board QFN-16

    The MPS EVQ9843-L-00A is an evaluation board built around the MPQ9843 for bench characterisation of the device in its intended topology. It operates from a 5 V to 36 V input, is rated for 3 A and switches at 450 kHz. The board carries the device in its QFN-16 package.

    The EVQ9843-L-00A Evaluation Board is designed to demonstrate the capabilities of MPS' MP/MPQ9843.

    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.
