Monolithic Power Systems (MPS) EV4255-VE-00A Evaluation Board
Monolithic Power Systems (MPS) EV4255-VE-00A Evaluation Board is designed to demonstrate the capabilities of the MP4255 converters. These MP4255 converters are dual-channel, monolithic, step-down converters with an I2C interface. Each channel can deliver up to 3A of output current, with excellent load and line regulation across a wide 4V to 36V input voltage range. The EV4255-VE-00A evaluation board is used in USB Power Delivery (PD) and USB Dedicated Charging Ports (DCP).
