XDPP1100-Q024 daughter board
General description
1 General description
The EVAL_XDPP1100_Q024_DB daughter board is used for testing and programming the XDPP1100
VQFN 4 mm x 4 mm 24-pin version controller. An onboard I2C connector allows the user to interface with
the XDPP1100 controller through Infineon’s graphical user interface (GUI) and a USB-to-I2C dongle. The
GUI is available to users as a complimentary tool that can be downloaded from Infineon Developer
Center. Searching the product part number XDPP1100, the XDPP1100 GUI will show up for
downloading.
The daughter board can be used as a standalone FW development tool, or used with a power board as a
complete evaluation kit. This document describes the standalone version of the daughter board. User
could order the daughter board (EVAL_XDPP1100_Q024_DB), a 600 W full-bridge power stage
(EVAL_600W_FBFB_XDPP), and an USB dongle (USB007A) to make an evaluation kit as shown in
Figure 1.
Figure 1 Evaluation kit
The daughter board uses board-to-board connectors (QTE-020-01-L-D-A) to interface control signals from
the daughter board to a power board with compatible connectors (QSE-020-01-L-D-A) to establish a plug-in
mechanism. This plug-in mechanism provides flexibility for evaluating XDPP1100 performance with any
of its supported topologies.
The board also provides the capability to use an IC socket (24QHC50A74040G) for easy replacement of
the XDPP1100-Q024 instead of soldering the device onto the PCB. The IC socket does not mounted on
the board and need to be purchased separately.
1.1 Daughter board overview
The daughter board consists of the control circuitry such as analog filters for processing feedback
signals from the power board, PWM outputs, digital inputs and outputs, I2C connector, Cortex®
JTAG/SWD debug port, LED indicators and the XDPP1100-Q024 controller. It can be powered using
external 3.3 V, or 3.3 V supply from the power board. The daughter board is shown in Figure 2. The
board-to-board rectangular header connectors are located on the bottom side of the PCB.

Power-up procedure
•Turn on the 3.3 V power supply. If the USB dongle is connected and the dongle driver is installed
properly, the USB icon at the bottom left corner will turn green. The USB hardware (HW) model and
dongle FW version would show in the information bar at the bottom. Also, update the dongle firmware
using the icon as shown below.
Figure 7 XDPP1100 GUI
•Use the auto-populate shortcut button to scan the device that is connected on the I2C bus. If the
XDPP1100 is properly biased, the GUI should identify the device part number and its address offset,
then add the device to the design. The GUI will read the stored program from the IC to the GUI. If the
XDPP1100 is not pre-programmed (blank IC when it leaves the factory), the registers and PMBus
command have the default values and most of them are zero.
Figure 8 Auto-populate
•The user can use the GUI design tool to program the device per application requirements (Figure 9).
All the configurations are in RAM. RAM is a volatile memory and can be used during the evaluation
phase to try different configuration settings without limitation. The XDPP1100 has 32 kB RAM, and 10
kB is reserved for the user. It is recommended to take advantage of the 10 kB RAM to verify patch
and configuration. Only the final configuration should be stored to device non-volatile memory which
is one-time programmable (OTP). The XDPP1100 has 64 kB available OTP space for FW patch and
configuration.
