DESCRIPTION
The EV5402M-R-00A 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 each 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.

Connect the positive and negative terminals of the load to the USB1, USB2 and GND pins, respectively. 2. Preset the power supply output between 7V and 36V, and then turn off the power supply. 3. Connect the positive and negative terminals of the power supply output to the VIN and GND pins, respectively. 4. Turn the power supply on. The board will automatically start up. 5. To use the Enable function, apply a digital input to the EN pin. Drive EN higher than 2V to turn on the regulator or less than 1V to turn it off.
