EV8847-D-00A 2.7-6V, 6A High Efficient Synchronous Step-Down Switcher Evaluation Board

The MPS EV8847-D-00A is an evaluation board built around the MP8847 for bench characterisation of the device in its intended topology. It operates from a 2.7 V to 6 V input and is rated for 6 A.

The MP8847 is a highly integrated and high frequency synchronous step-down switcher with I2C control interface.

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.
