EV5402M-R-00B 5A, 36V, Frequency Selectable Step-Down Converter with Dual USB Charging Ports The Future of Analog IC Technology DESCRIPTION FEATURES The EV5402M-R-00B Evaluation Board is designed to demonstrate the capabilities of MPS’ MP5402M. MP5402M integrates a monolithic step-down switch mode converter and two USB current limit switches with charging port identification circuit. It achieves 5A continuous output current over a wide input supply range with excellent load and line regulation. • • The output of USB switch is current limited. Both USB ports support DCP schemes for Battery Charging specification (BC1.2), the Divider Mode, and 1.2V/1.2V Mode without the need for outside user interaction.
