EV3221-J-00A 2.5-6V, 2.7A Step up Converter With Input Disconnection EV board Evaluation Board TSOT23
The MPS EV3221-J-00A is an evaluation board built around the MP3221 for bench characterisation of the device in its intended topology. It operates from a 2.5 V to 6 V input, is rated for 2.7 A and switches at 1.2 MHz. The board carries the device in its TSOT23 package.
The MP3221 is a 1.2MHz frequency, 6-pin TSOT23 current mode step up converter intended for small, low power applications.

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.
