EV2326-D-00A 4A Constant-On-Time Step-Down Switcher Evaluation Board QFN14

The MPS EV2326-D-00A is an evaluation board built around the MP2326 for bench characterisation of the device in its intended topology. It is rated for 4 A. The board carries the device in its QFN14 package.

The EV2326-D-00A is used for demonstrating the performance of MP2326, a fully-integrated, high efficiency, synchronous step-down switch mode converter with the feathered 40uA quiescent current.

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.
