EV8859-Q-00B 2.8-22V 2.8V-22V Vin, 3A Iout, 4-Switch Integrated Buck-Boost Converter Evaluation Board
The MPS EV8859-Q-00B is an evaluation board built around the MP8859 for bench characterisation of the device in its intended topology. It operates from a 2.8 V to 22 V input, is rated for 3 A and switches at 500 kHz.
The EV8859-Q-00B is an evaluation board for MP8859, which is a synchronous 4-switch integrated buck-boost converter.

Evaluation Board
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.
