Monolithic Power Systems (MPS) EV2770-L-00A Evaluation board

Monolithic Power Systems (MPS) EV2770-L-00A Evaluation board is designed to demonstrate the capabilities of the MP2770, a switchmode battery charge and system power path management device. This MP2770 meets most of the system’s power demand and input power using the V_IN regulation function and input current limit (I_{IN_LIM}). The evaluation board features 5V to 15V input sources, wall adapters, and standard USB host ports with fast charging capabilities. This evaluation board operates at 600kHz switching frequency, 4V to 16V input voltage range, and 6A maximum battery current. The MP2770 battery management is designed for Li-ion, Li-polymer, and single-cell batteries across various portable applications.
