EV2147-D-00A 2.8-5.5V, 4A Step-Down Switcher Evaluation Board QFN2
The MPS EV2147-D-00A is an evaluation board built around the MP2147 for bench characterisation of the device in its intended topology. It operates from a 2.8 V to 5.5 V input, is rated for 4 A and switches at 1.2 MHz. The board carries the device in its QFN2 package.
The MP2147 is a monolithic, step-down, switch- mode converter with internal power MOSFETs.

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.
