EV5408M-U-00A Smart, Dual USB Charging Port Power Converter with Programmable Frequency DESCRIPTION FEATURES The MP5408M integrates a monolithic stepdown switch-mode converter with two USB current-limit switches and charging port identification circuitry for each port. It achieves 6A output current over a wide input-supply range with excellent load and line regulation. The output of the USB switch is current limited. Both USB ports support DCP schemes for Battery Charging specification (BC1.2), the Divider Mode, 1.2V/1.2V Mode and USB TYPEC 5V@3A DFP Mode eliminating outside user interaction.

Connect the positive and negative terminals of the load to the USB1, USB2 and GND pins, respectively. A I 2. Preset the power supply output between 6V 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 T N pins, respectively. 4. Turn the power supply on, the board will automatically start up. But if no type-C device is attached, there is no Vbus output. E 5. For USB Type-C 5V/3A DFP mode, if no type-C device is attached, connect R3 =5.1kΩ resistor E to enable USB1output，connect R4 =5.1kΩ to enable USB2 output; Connect R5 =1kΩ resistor D I T to enable VCONN1 output, connect R6=1kΩ resistor to enable VCONN2 output. 6. For USB Type-A 5V/2.4A mode, connect R3 =80.6kΩ resistor to enable USB1output, connect F R4 =80.6kΩ resistor to enable USB2 output. Keep R5, R6 float.
