USER GUIDE –MP5515 EVALUATION KIT (EVKT-5515)
Overview
Introduction
The EVKT-5515 is an evaluation kit for the MP5515, an input-power-conditioning PMIC targeting
enterprise solid-state drives, NVDIMM, and other applications with back-up system requirements. The
MP5515 consists of input current limiting, input reverse-current blocking, and an MPS-patented, high-
efficiency, bidirectional, boost-buck converter with only one inductor for energy storage and system
back-up power when there is an input power failure. This kit allows for quick evaluation of the MP5515.
By using the I2C, users can set the input current limit, slew rate, and perform cap health tests.

Section 3. Evaluation Kit Test Set-Up
3.1 Hardware Set-Up
The hardware must be configured properly prior to use. Use the USB cable to connect the EVKT-
USBI2C-02 communication interface to the PC, and 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 VB and GND pins, respectively.
2. Preset the power supply output to 12V, and then turn off the power supply.
3. Connect the positive and negative terminals of the power supply output to the VIN and GND pins,
respectively.
4. Turn the power supply on. The MP5515 will enter the power-on sequence automatically.
3.3 Software Set-Up
After connecting the hardware according to the above steps, follow the steps below to use the GUI
software.
1. Start the software. It will automatically check the EVB connection.
•
If the connection is successful, the address will be listed in the “Slave Address” (see Figure 7).

•
If not, a warning will appear at the bottom. There are two warnings users can expect.
1) “No Slave Found. Please Check the Connection!”This means that the evaluation board is
not connected (see Figure 8).
2) “Device is not available. Please check the Connection!”This means that the USB I2C
communication interface is not connected (see Figure 9).

3.4Troubleshooting Tips
Note: USBI2C-02 and USBI2C-01 drivers are not compatible. USBI2C-02 uses USBXpress and
USBI2C-01 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 12).
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
13).
1. Browse the thumb drive contents and open the
driver’s folder.
2. 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
3. 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 MP5515 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.
