5. If user modified below function:
1. I2C slave address function(D[4:0] bits in 0x0D I2C register)
2. ADD_PG_OP_SYNCOUT function(D[7:6] bits in 0x0E I2C register)
I2C slave address may be changed immediately after the operation. Press the Detect button again
and select the new I2C slave address before other I2C register modifications or MTP actions.
Figure 13: Refresh Device’s I2C Address after the Modification of “I2C SLAVE ADDRESS” Function
As shown in Figure 13, after changing the I2C slave address function related bits (D[4:0] bits in
0x0D I2C register) from “01000” default value to “00000”, the new I2C slave address ”0x60” will
take effect immediately. Press the Detect button again and select the new I2C address before
taking any other action.
6. The MTP registers configuration file can also be exported by clicking “Utility—MTP/OTP--Export”.
Afterward, the software interface will be as shown in Figure 14.

7. Choose the RAMP value setting for Buck 1 to Buck 4. Enter the suffix code (work with an MPS
FAE to get this unique number or refer to the DS ordering information section for details) and OTP
version number. Click “OK”. Find a location for the exported file and click “OK” again. Your MTP
registers configuration will be saved into a text file (.txt) with the file name format: MP5470GR-0011
(MTP configure code) -rev0000 (MTP revision number). Send this text file to an MPS FAE to order
the MP5470 C-spec IC following the MTP configuration in it.

8. Click the MTP Configure tab to save the changes to the IC. Fill in the MTP configure code, MTP
version number, and correct MTP program password (NOTE: the MTP Program button will be
invalid with the wrong password). The MTP program password is “mps0519”.
Figure 16: Burn MTP Action Ongoing
9. Click the MTP Program button. The GUI will be as shown in Figure 17. Click the Read All button.
The 0x13 register value changing from 0x81H to 0x82H indicates a successful MTP.

10. NOTE: the MP5470 can be programmed three times. It will be ineffective if the program time is
larger than three.
The remaining steps are optional and instruct how to check that new configurations have been
successfully programmed.

Optional:
11. Adjust the input voltage to 6.5-12V.
12. Repeat steps 1-3 from this section.
13. If done correctly, new configurations will be shown in the table on the right hand side.
Notes:
Unlike in I2C, not all of the configurations set in MTP mode will be displayed until a MP5470-0000
write and power cycle.
After MTP, the values can still be changed using the I2C.
If you attempts to perform MTP on a device that already been programmed three times, the GUI
software will allow you to proceed normally. However, your configurations will NOT be saved.
3.5 Troubleshooting Tips
Note: USBI2C-02 and USBI2C-01 drivers are not compatible. USBI2C-02 uses USBXpress and
USBI2C uses Cyusb3. USBI2C-02 is the recommended device for MPS PMBus and I2C.
EVKT-USBI2C-01
In case that the USBI2C-01 driver is not properly
installed, manual installation is required. Follow the
steps below.
1. Open the Device Manager and select update driver
software (see Figure 18).
2. Click “Browse my computer for driver software”, find
the driver located on thumb drive and install.
EVKT-USBI2C-02
In the case that the USBI2C-02 driver is not properly
installed, manual installation is required. Follow the steps
below.
Note: Check driver version. Find “USBXpress” Device in
the Device Manager under USB controllers.
Right click and view properties. Check to make sure the
driver version matches the newest version (see Figure
19).
1. Install the correct USBXpress “.exe” file.
Choose either 32 bit or 64 bit operating system.
32-bit: USBXpressInstaller_x86.exe
64-bit: USBXpressInstaller_x64.exe
2. Connect the EVKT-USBI2C-02 Dongle to the PC with
the USB cable.
