Monolithic Power Systems MP2650 | Demoboard EV2650-V-01A – 5A

Description

The EV2650-V-01A is an evaluation board designed for the MP2650, a highly integrated buck or boost charger IC with narrow-voltage DC (NVDC) power path management and USB On-the-Go (OTG) for battery packs with 2 cells, 3 cells, and 4 cells in series. The integrated power MOSFETs provide a compact system solution size that is easy to use.The device can accept a wide input voltage (VIN) range (up to 21V) for charge mode. This device has two operating modes while charging: boost charging mode and buck charging mode. The mode is determined by the input voltage and cell count. The MP2650 can also provide a constant voltage (5V/3A) at input in USB OTG mode. With the I2C interface, the MP2650 can be flexibly configured to set the parameters in both charge mode and OTG mode. It can also provide the operation status through status and fault registers.The MP2650 is available in a QFN-30 (4mx5mm) package.
