Monolithic Power Systems MP4246 | Demoboard EVL4246-V-00A

Beschreibung

The EVL4246-V-00A evaluation board is designed to demonstrate the capabilities of the MP4246, a synchronous, four-switch buck-boost converter with integrated MOSFETs. The device can deliver up to 6A of output current (IOUT) at certain input supply ranges with excellent efficiency.The MP4246 is well-suited for USB power delivery (PD) and wireless charging applications. It can work with an external PD or wireless charging controller through the I2C interface.It is recommended to read the MP4246 datasheet prior to making any changes to the EVL4246-V-00A.
