QUICK START GUIDE
MCU Mode:
1. Connect the battery pack to the BATT (TP1) and GND (TP2) connectors. Ensure the battery
positive/negative terminals are not reverse connected.
2. If using a battery emulator, preset the battery emulator to 3.8V/5A and turn off the emulator.
Connect to BATT (TP1) and GND (TP2), then turn on the emulator output.
3. Plug in the input adapter to the micro-USB port (P2), or connect the input power source (5V/3A) to
the VIN (TP3) and GND (TP4) terminals. The MP2696A should start charging the battery.
4. To test the boost output, plug in the load USB cable to the USB-A (P1) port, or add the load on the
SYS (TP5) and GND (TP6) terminals. The boost should start automatically.
5. Pressing the SW1 button also activates the SYS output.
6. If no load is present at the SYS output after 32 seconds, the MP2696A turns off boost mode and
enters sleep mode automatically.
7. Charge first to avoid BATT_UVLO lockout.
8. Contact MPS for information regarding the MCU code.
I2C Communication Interface Mode:
1. Install the USB communication interface driver on the computer, and connect the communication
interface to the SCL/GND/SDA connector on the board.
2. Remove the shunts on JP2 and JP3.
3. Connect the battery pack to the BATT (TP1) and GND (TP2) connectors. Ensure the battery
positive/negative terminals are not reverse connected.
4. If using a battery emulator, preset the battery emulator to 3.8V/5A and turn off the emulator.
Connect to BATT (TP1) and GND (TP2), then turn on the emulator output.
5. Verify that the USB communication interface connects the MP2696A to the computer successfully
(the GUI will show no warning notification of unsuccessful connection).
6. The charging and boost parameters can be controlled by the GUI interface.
