EV2172-J-00A 2.5-5.5V, 2A Synchronous Step-Down Switcher Evaluation Board TSOT23
The MPS EV2172-J-00A is an evaluation board built around the MPQ2172 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 2 A and switches at 2.6 MHz. The board carries the device in its TSOT23 package.
The EV2172-J-00A is used for demonstrating the performance of MPS's MP/MPQ2172, a low voltage high switching frequency step-down switcher with built in 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.
