Overview
Introduction
Optimized Performance with MPS MPL-AL5030 Inductor Series
The EVKT-MP2760 is an evaluation kit for the MP2760. The board is designed to demonstrate the
capabilities of the MP2760, a buck-boost narrow-voltage DC (NVDC) charger IC for battery packs with 1
to 4 cells in series. The device accepts a wide 4V to 22V input voltage (VIN) range to charge the battery
and power the load connected on the SYS pin. It also supplies a wide 3V to 21V voltage range at the IN
pin when source mode is enabled, which is compliant with USB powered device (PD) specifications.

Section 3. Evaluation Kit Test Set-Up
3.1 Hardware Set-Up (2)
The hardware must be properly configured prior to use. Follow the instructions below to set up the EVB:
1. Connect the EVB to the EVKT-USBI2C-02 communication interface with the 3-pin ribbon cable and
ensure they are connected.
2. Connect SCL, SDA, and GND (see Figure 6). If needed, refer to the MP2760 datasheet for further
clarification.
3. Connect the EVKT-USBI2C-02 to the computer.
Note:
2) It is important to adhere to the order of these steps. Failing to do so may cause damage to the communication pins (SCL and SDA) during
a hot plug event.

3.3 Software Set-Up
After connecting the hardware according to the steps above, follow the steps below to use the GUI
software:
1. Start the software. It should automatically check the EVB connection.
•If the connection is successful, “Device connected” is listed at the bottom (see Figure 7).
Figure 7: Status Shows Successful Connection
•If the connection is unsuccessful, a warning appears at the bottom. There are two warnings that
the user can expect:
o“Device disconnected” means that the evaluation board is not connected correctly (see Figure
8 on page 10).

o“USB disconnected” means that the USB to I2C communication interface is not connected
correctly (see Figure 9).
Figure 8: Warning Indicates Unsuccessful Evaluation Board Connection
Figure 9: Warning Indicates Unsuccessful USB I2C Communication Interface Connection
2. If the connection is successful, proceed to Step 3. Otherwise, check connections between the EVB,
communication interface, and PC. Re-plug the USB into the computer and restart the GUI.
3. Click the “Read All” button to read the I2C register values. The default values are displayed (see
Figure 10 on page 11).
4. Find the item to be changed, then select the desired value from the drop-down menu.
5. Click the “Write All”button to update the values. The changed information should download to the IC.
 All changes made via the I2C are restored to their default values once the EVB shuts down.

3.4 Device Programming Instructions
The MP2760-xxxx is a one-time programmable (OTP) part, where “-xxxx” is the register setting option.
The factory default is “-0000,” and this content can be viewed in the I2C register map. Follow the
instructions outlined below to create and export customized configurations:
1. Using a computer, open the MPS GUI software. Make sure you have powered on the EVB.
2. Ensure connection between the EVB and computer.
3. Select “OTP View” under OTP in the toolbar (see Figure 11).

3.5 Troubleshooting Tips
EVKT-USBI2C-02 Driver Installation Problem
If the USBI2C-02 driver is not properly installed, manual installation is required. Follow the steps below
to manually install the EVKT-USBI2C-02 driver:
Note: Find “USBXpress Device” in the Device Manager.
If the PC is running Windows 10, check the driver version of USBXpress Device. Windows 10
automatically installs the older USB driver, which is not compatible. The correct driver version is 4.0.0.0
(see Figure 15 on page 13).
1. Install the correct "USBXpress “.exe” file. Choose either the 32-bit or 64-bit operating system.
32-bit: USBXpressInstaller_x86.exe
64-bit: USBXpressInstaller_x64.exe
2. Connect the EVKT-USBI2C-02 communication interface to the PC with the USB cable.

No Supply
The IC’s input pin has an under-voltage lockout (UVLO) detection circuit. If the input voltage (VIN) is below
the UVLO rising threshold, the PMIC’s functions are disabled.
Shutdown Event
If the IC detects that VIN is below the UVLO falling threshold (enter no supply state) or over-temperature
protection is triggered (enter shutdown state), then the IC switches to a no supply state or shutdown
state, regardless of the current state.
Thermal Recovery
If the MP2760 is in a shutdown state due to the die temperature exceeding the thermal protection
threshold, then the IC starts up again once the die temperature decreases.
