4.2.1 PF5023: Power management integrated circuit (PMIC) for high performance
applications
4.2.1.1 General description
The PF5023 integrates multiple high performance buck regulators. It can operate as a
stand-alone point-of-load regulator IC, or as a companion chip to a larger PMIC.
Built-in one-time programmable (OTP) memory stores key startup configurations,
drastically reducing external components typically used to set output voltage and
sequence of regulators. Regulator parameters are adjustable through high-speed I2C
after start up offering flexibility for different system states.
4.2.1.2 Features
• Three high efficiency buck converters
• VTT Termination mode on SW2
• Watchdog timer/monitor
• Monitoring circuit to fit ASIL B safety level
• One-time programmable device configuration
• 3.4 MHz I2C communication interface
• 40-pin QFN package with wettable flank and exposed pad

3. Disconnect and reconnect the USB cable into the SDA port (this time without pressing
the RST push button). The PC installs a new device called FRDM_KL25Z.
4. Locate the file nxp-gui-fw-frdmkl25z-usb_hid-pf502x_v0.1.6.bin from the MCU
folder and drag and drop the file into the FRDM_KL25Z device.
5. Freedom board firmware is successfully loaded.
6. Open and run the NXP_GUI-1.0-Setup.exe file from the GUI folder inside the
unzipped package. This installs the NXPGUI software in the system. Install it in a local
destination folder.
6Configuring the hardware for startup
To configure the hardware and workstation, complete the following procedure:
1. With the USB cable connected to the PC and the USB port in the freedom board,
apply VIN to the evaluation board.
a. Provide external VIN between 2.5 V to 5.5 V on J10 (VIN) and J4 (GND). Make
sure that the supply is current limited to 100 mA.
2. Press Reset on the Freedom board, to ensure board is properly recognized.
3. If the NXPGUI application was not installed before, perform step 6 of Section 5.1
"Freedom board BOOTLOADER refresh in a Windows 7 or 10 system (optional - only
when the Freedom board is not preprogrammed)" to install it for the first time. Open
the NXPGUI application from the installation folder or from the Start menu.
4. A configuration window is displayed. Select one of the devices to load the predefined
5. The NXPGUI interface should open and load the main framework. Make sure to
confirm if the GUI can identify the USB device properly. This is displayed by the active
Start button on the top-left corner of the GUI.
Note: The USB cable should be connected for the GUI to recognize and be able to
connect to the device.
6. Click Start to enable the connection to the device. The device status can be read from
the bottom-left corner of the GUI.
7. Once the device is connected, the system is ready for Hardwire, TBB or OTP
This section summarizes the overall setup. Detailed description is provided in the
following sections.
7.1 Operating in Hardwire mode
To operate the board with the default hardwire configuration, complete the following
procedure:
1. Short J34 in position 2-3 and SW17 in position 1 (PWRON = high) or leave J34 open
to let the MCU on the board control the pin.
2. Short J39 in position 2-3 (VDDOTP = V1P5D).
3. Short J40 in position 1-2 (TBBEN = Low).
In Hardwire mode, applying power to the board turns On the device by default. However,
when the GUI is started, and the device is connected, the PMIC turn On/Off can be
controlled via the PWRON control in the IO Pins tab of the main window.

7.2 Operating in TBB mode
To operate the device in TBB mode, an TBB script can be created using the OTP section
of the NXPGUI (installed in the previous steps).
To generate a TBB script, complete the following procedure:
1. Select the configuration settings in the OTP tool as required.
2. Generate a TBB script using the Export section on the OTP tool (make sure to fill all
required fields marked with a * next to them). Save the generated TBB file in a known
location.
To operate the board in TBB mode, complete the following procedure:
1. Set SW17 to position to 3 (PWRON to GND).
2. Short J40 in position 2-3 (TBB = V1P5D).
Or
3. Use the NXPGUI to select the TBB mode, when the KL25Z interface board is
connected to the EVB. Disconnect jumpers J40, J34, J41, and J42 from the board as
explained in Section 4.2.2 "Jumper, switch, and shunt configuration".
4. In the Script section of the GUI, use the command window to load the TBB script
created and click Run to start programming the PF5023.
5. After Script is done programming, the device is automatically enabled with the
selected TBB configuration.
7.3 Programming/burning OTP in TBB mode
To program the OTP, the device must be operated in TBB mode. An OTP script can be
created using the NXPGUI OTP section.
1. Start the NXPGUI from the installation folder or from the Start menu. Follow the steps
in Section 6 "Configuring the hardware for startup" to start the GUI and connect to the
board.
2. Generate the desired OTP configuration and the configuration using the file menu on
default of the applications and the products or of the application or use by
customer’s third party customer(s). NXP does not accept any liability in this
respect.
