EV2322-D-00A 3-22V, 1A Low IQ Step Down Converter Evaluation Board NOT RECOMMENDED FOR NEW QFN-8
The MPS EV2322-D-00A is an evaluation board built around the MP2322 for bench characterisation of the device in its intended topology. It operates from a 3 V to 22 V input, is rated for 1 A and switches at 1.25 MHz. The board carries the device in its QFN-8 package.
The EV2322-D-00A Evaluation Board is designed to demonstrate the capabilities of MPS' MP2322,a high light load efficiency synchronous rectified step-down switch mode converter with built in 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.
