Monolithic Power Systems (MPS) EVKT-MP2722 Evaluation Kit

Monolithic Power Systems (MPS) EVKT-MP2722 Evaluation Kit is used to demonstrate the capabilities of the MP2722 buck chargers. These buck chargers are single-cell, 5A, Narrow-Voltage DC (NVDC) buck chargers with USB Type-C™ Dual-Role Power (DRP) detection and serial interface control. The device can charge the battery with a 4V to 16V input voltage (V_IN). The default function of this board is preset for charger mode, and the charge-full voltage is preset to 4.2V for a single-cell Li-ion battery. The EVKT-MP2722 evaluation kit includes an MP2722 evaluation board, one USB-to-I²C communication interface, one USB cable, and one ribbon cable. This MP2722 evaluation board can be used in Bluetooth headphones, Bluetooth speakers, Point-of-Sale (POS) terminals, and portable cameras.
