EV2319-J-00A 4.5-18V, 3A Step Down Converter Evaluation Board TSOT23

The MPS EV2319-J-00A is an evaluation board built around the MP2319 for bench characterisation of the device in its intended topology. It operates from a 4.5 V to 18 V input, is rated for 3 A and switches at 650 kHz. The board carries the device in its TSOT23 package.

The MP2319 is a fully-integrated high- frequency, synchronous rectified, 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.
