Section 2. Software Requirements

2.1 Software Installation Procedure

Programming occurs through the MPS I2C GUI. Follow the instructions below to install the software.

Note: This software can be downloaded from the MPS website:

1. Download and extract the zip package of the “I2C evaluation kit software for MP2663” to a directory

of your choice.

2. Double click the .exe file to open the set-up guide (see Figure 4).

3. Follow the prompts in the set-up guide.

4. Wait for status screen to verify that installation is complete (see Figure 5).

Section 3. Evaluation Kit Test Set-up

3.1 Hardware Setup

The hardware must be properly configured prior to use. Follow the instructions below to set up the EVB.

1. Locate the proper wires to connect the EVB to the EVKT-USBI2C-02 communication interface.

2. Connect SCL, SDA, and GND (see Figure 6). If needed, refer to the datasheet for further clarification.

Figure 6: EVB to MPS I2C Communication Interface Wire Connection

3.2 Powering up the EVB

1. Connect the positive and negative terminals of the load to the SYS and GND pins, respectively.

2. Connect the positive and negative terminals of the battery to the VBATT and GND pins, respectively.

If it is a battery simulator, preset the battery voltage between 0V and 4.545V, then turn it off. Connect

the battery simulator output to the VBATT and GND pins respectively.

3. Preset the power supply output between 3.9V and 7.0V, and then turn off the power supply. Connect

the positive and negative terminals of the power supply output to the VIN and GND pins, respectively.

4. Make sure the battery voltage has been preset (if a battery simulator is used, turn on the battery

emulator). Turn the power supply on. The IC will enter the power on sequence automatically.

Reminder: if the battery simulator is connected, please make sure to turn on the battery emulator first,

before the input supply in the start-up sequence.

3.3 Software Set-Up

After connecting the hardware according to Section 3.1 and Section3.2, follow the steps below to use the

GUI software:

1. Start the software. It will check the EVB connection automatically.

If connection is successful, both the USB and MP2663 DEMO board statuses are "connected".

(See Figure 7).

Figure 7: Appearance of USB and MP2663 EVB Board Show Connected

If connection is not successful, "Not Connected" will appear in red. Check connections between

the EVB, communication interface, and PC. Re-plug the USB into the computer.

1) MP2663 DEMO Board “Not Connected" means that the evaluation board is not connected

correctly.

2) USB “Not Connected" means that the USB I2C communication interface is not connected

correctly.

2. Click the “Read All Register” button to read the I2C register values and the default values are

displayed (see Figure 7).

3. Find the item you want to change and select the desired value from the drop down menu.

4. Click the “Write All” button to update values. The changed information of the item will be downloaded

to the IC.

All changes made via the I2C will be restored to default values once the EVB is powered down.
