USER GUIDE – MP5470 EVALUATION KIT (EVKT-MP5470) Overview Introduction The EVKT-MP5470 is an evaluation kit for the MP5470, a complete power management IC with four high-efficiency, step-down, DC/DC converters and flexible system configurations via the I C and a multi-time programmable (MTP) eFuse. The kit allows for quick evaluation of the PMIC and offers MTP capabilities, which allows users to program custom configurations three times maximum, supporting a wide range of designs.
USER GUIDE – MP5470 EVALUATION KIT (EVKT-MP5470) Features and Benefits The MP5470 is highly customizable. Users can program the PMIC via the MPS I2C GUI and multi-time programming (MTP). ⚠️ All changes made in I2C mode will NOT be retained once the EVB is powered down.
EVB and the PC, and its supporting accessories. It provides I2C and PMBus capabilities. Together with MPS Virtual Bench Pro and GUI tools, it provides a quick and easy way to evaluate the performance of MPS digital products. For more details, refer to the EVKT-USBI2C-02 datasheet.
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 directly from the MPS website. . 1. Browse to the folder containing the thumb drive contents.

PC. Re-plug the USB into the PC and restart the GUI. 3. Select MP5470 from under Part Numbers. The Register Control menu will appear on the left side. I2C register values will be read automatically and displayed on the right (see Figure 10).
All changes made via the I2C will be restored to default values once the EVB is powered down. 3.4 Device Programming Instructions The MP5470 can be custom programmed and saved to the PMIC. Follow the instructions outlined below to create and export customized configurations.

The 0x13 register value changing from 0x81H to 0x82H indicates a successful MTP. Figure 17: Burn MTP Action Success 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.
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.
Includes one USB to I2C communication interface device, one USB EVKT-USBI2C-02 cable, and one ribbon cable MP5470GR-0000 MP5470 ICs which can be used for MTP programming Order directly from MonolithicPower.com or our distributors.
