EV2238-D-00A 4.2-18V, 8A High-Efficiency Evaluation Board
The MPS EV2238-D-00A is an evaluation board built around the MP2238 for bench characterisation of the device in its intended topology. It operates from a 4.2 V to 18 V input, is rated for 8 A and switches at 600 kHz.
The EV2238-D-00A Evaluation Board is designed to demonstrate the capabilities of MPS' MP2238, a fully-integrated high-frequency, synchronous rectified, step-down, switch-mode converter with internal power MOSFETs.

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.
