EV2639A-R-00A 4-5.75V, 2.5A Reference Design Evaluation Board

The MPS EV2639A-R-00A is an evaluation board built around the MP2639A for bench characterisation of the device in its intended topology. It operates from a 4 V to 5.75 V input and is rated for 2.5 A.

The EV2639A-R-00A is the reference design board for MP2639A, a highly-integrated, flexible switch-mode battery charge management for 2- cell series Li-ion and Li-Polymer battery used in a wide range of 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.
