EV3421-G-00A 1.9-5.5V, 5.5A Synchronous Step-up Converter Evaluation Board QFN2

The MPS EV3421-G-00A is an evaluation board built around the MP3421 for bench characterisation of the device in its intended topology. It operates from a 1.9 V to 5.5 V input, is rated for 5.5 A and switches at 600 kHz. The board carries the device in its QFN2 package.

EV3421-G-00A Evaluation Board is designed to demonstrate the capability of MP3421.

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.
