Monolithic Power Systems (MPS) EVKT-MP2651 Evaluation Kit

Monolithic Power Systems (MPS) MP2651 Evaluation Kit is used to evaluate the MP2651 buck-boost charger IC. The Monolithic Power Systems (MPS) MP2651 is designed for battery packs with 1 to 4 cells in series. The EVKT-MP2651 showcases the capabilities of this device. The device features a broad input voltage range of 4V to 22V and the ability to supply a wide 3V to 21V voltage range at the IN pin in source mode. The MP2651 is compliant with the USB PD specification.
