EV2143H-D-00A 2.5-5.5V, 3A Synchronous Step-Down Switcher Evaluation Board QFN10
The MPS EV2143H-D-00A is an evaluation board built around the MP2143H for bench characterisation of the device in its intended topology. It operates from a 2.5 V to 5.5 V input, is rated for 3 A and switches at 2 MHz. The board carries the device in its QFN10 package.
The EV2143H-D-00A is used for demonstrating the performance of MPS's MP2143H, a monolithic, 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.
