Monolithic Power Systems MP4248 | Demoboard EVL4248-QV-00A

Description

The EVL4248-QV-00A evaluation board is designed to demonstrate the capabilities of the MP4248, a buck-boost converter with two low side MOSFETs (LS-FETs). The device can deliver up to 140W of peak output power (POUT) at certain input-supply range with excellent efficiency.The MP4248 is well-suited for USB power delivery (PD) applications. It can work with an external USB PD controller through the I2C interface.It is recommended to read the MP4248 datasheet prior to making any changes to the EVL4248-QV-00A.
