Overview
Introduction
The EVKT-5416 is an evaluation kit for the MP5416, a complete power management IC, which integrates
four high-efficiency, step-down, DC/DC converters, five low dropout regulators, and flexible system
configurations via the I2C. The kit allows for quick evaluation of the PMIC and offers one-time
programming (OTP) capabilities, which allows users to program custom configurations, supporting a wide
range of designs.

The remaining steps are optional and instruct how to check that new configurations have been
programmed.
Optional:
17. Adjust the input voltage to 3.5 - 5V.
18. Repeat steps 1-3 from this section.
19. If done correctly, new configurations will be shown in the table on the left hand side.
Notes:
Unlike in I2C, not all of the configurations you set in OTP mode will be displayed until you write to
MP5416-CCCC and power cycle.
After OTP, you:
oAre still able to change values using the I2C.
oDo not need to press P1 while powering on the board.
If you try to perform OTP on a previously programmed device, 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 19).
2. Click “Browse my computer for driver software”, find the downloaded driver and install.
Figure 19
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 20)

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.
No Supply
The PMIC’s input pin has an under-voltage lockout (UVLO) detection circuit. If the input voltage (AVIN)
is lower than the UVLO rising threshold, the PMIC’s functions are disabled.
Shutdown Event
If the PMIC detects that the input voltage is lower than the UVLO falling threshold (enter no supply state)
or over-temperature protection is triggered (enter power off state), the PMIC switches to no supply state
or power-off state, regardless of the current state.
Thermal Recovery
If the MP5416 is in a power-off state due to the die temperature exceeding the thermal protection
threshold, the PMIC enters a power-on sequence when the die’s temperature decreases.
Shutdown Sequence
When the input voltage is lower than the UVLO falling threshold or the IC is over-temperature, the PMIC
enters the shutdown sequence directly.
