Therefore the use of a USB2.0 port is recommended (which can be provided by an external USB2.0 hub if the machine offers USB3.0 ports only). Connect the.dp Interface Gen2 with the Programming Cable to the XDPL8220 Reference Board Figure 2.dp Interface Gen2 Connection Note: Please ensure that the connector of the Programming Cable is plugged in correctly: the red wire indicates the Pin 1 and should be connected to the Pin Vcc on the XDPL8220 Reference Board.

Application Note 6 Revision 1.0

7 2.2 Software Installation After the required software tools are downloaded, please follow the steps below to make the correct software installation. Install first the.dp Vision software. After the.dp Vision is successfully installed, please install the project addon. After the.dp Vision and project addon are successfully installed, four sub folders are created under the.dp Vision folder as shown in the following Figure 6: Figure 6 Four Sub-folders Under.dp Vision Note: Please use the shortcut generated on the desktop to access to these folders quickly! In the Documents folder you will find all the related documentation like datasheet, board description, CSV file description and Design guide. Attention: Please make sure that before getting started to operate the XDPL8220 reference board, read the XDPL8220 Board Description thoroughly. A wrong operation of the reference board could be dangerous to health and even to life! In the DpIfGen2_FW folder, the firmware of the interface board.dp Interface Gen2 is stored. Attention: Please make sure that the firmware version of the interface board for XDPL8220 has always a format of dpifgen2_rev2-x-x.hex. If the firmware version has a format of dpifgen2_rev1-x-x.hex (f.g. for XDPL8105), please update if first or it will show error message when connecting to XDPL8220. In the Images folder, the images related to the XDPL8220 parameters CSV file are stored. Attention: Please make sure that the all necessary images are stored in this folder. If any image is missing, the CSV file will not be opened by the.dp Vision and an error message will show. In the Parameters folder, the XDPL8220 parameters CSV file is stored. Application Note 7 Revision 1.0

8 3 Getting Started After the correct hardware connection and software installation, please follow the steps below to get started with the operation of the XDPL8220 reference board and parameterization. Start the.dp Vision program by clicking the shortcut.dp Vision on the desktop as the following Figure 7 shows. Figure 7 Starting.dp Vision Attention: During the program startup, if the system shows there is a newer version of.dp Vision, please kindly follow the procedures and update it accordingly. Open the XDPL8220 parameters configuration file (*.csv) in the folder \Infineon Technologies AG\.dp vision\parameters as shown in the following Select XDPL8220 configuration CSV file to open Figure 8 Open the CSV File Application Note 8 Revision 1.0

9 After opening the parameter csv file, a list of XDPL8220 configurable parameters will shown (see the box on the left in Figure 9). These values can be then modified by users and will turn blue. Attention:.dpVision will check the plausibility of the parameters values which are input by the user. If any value violates the limits, the value will turn red and an error message will appear in the message bar as shown in Figure 9. The limits may also be dependent on other user inputs. Users are not allowed to save, test or burn the configuration if there is error detected. Message Bar List of configurable parameters Figure 9 Changing Parameter Values in.dp Vision There are 2 options available to configure the IC based on the parameter values in.dp Vision. Burn Configuration As the XDPL8220 chip on the 50W reference design PCB was already permanently burned with a first full set of parameters in its one time programmable (OTP) memory space, any parameter value change using this option is considered as parameter patching. The OTP memory space which is dedicated for patching or burning the parameter value change has a memory size of 274 words. Each time when the burn configuration function is executed, it will detect if there is parameter value difference between the saved configuration file and the target XDPL8220. If there is difference detected, each burn configuration will consume minimum 3 words depends on how many parameters need to be patched. However, the process will be aborted if it consumes more memory space than what is remaining in the target IC. As a result, the user will have to replace the target IC with a new XDPL8220 chip, in order to burn the configuration. Table 3 below shows the recommended procedures of using burn configuration function in.dp Vision to patch the parameter into the OTP memory. Application Note 9 Revision 1.0

10 Table 3 Step Burn Configuration procedures Instruction I Open configuration file (see example in Figure 9) II III If necessary, change any parameter value then press [File] >> [Save] or [File] >> [Save as], to save the configuration file. Otherwise, proceed to step III Ensure that the primary supply voltage (e.g AC input) to the board is switched off or disconnected and the hardware connection for configuration is ok based on Figure 2 and Figure 3 IV Press to supply power and establish connection to the target XDPL8220. After this step, XDPL8220 will be in configuration mode and the device status should change to. V Press to burn configuration into target XDPL8220 After this step, you should see a pop-up window, which is similar to one of these below. OR VI Press Proceed or Yes to burn the configuration After this step, you should see a pop up window which shows the burning is successful. VII Press OK on the pop up window then disconnect the programming cable from board connector and test the application, if needed. Test Configuration This function will download the parameter values from the list in.dp Vision into the XDPL8220 RAM memory space and it will then be followed by an automatic IC startup for application testing with the new configuration. Unlike using the burn configuration, parameters configuration with this option is not permanent because the loaded RAM content will be lost once the IC supply voltage is turned off or the IC restarts due to certain protection. The advantage of using this option is it does not consume OTP memory space, thus there is no limit on the amount of parameter value changes. Application Note 10 Revision 1.0

11 Table 4 below shows the recommended procedures of using test configuration function in.dp Vision to load the new parameter values in the RAM and test the application with the new configuration. Table 4 Step Test Configuration procedures Instruction I Open configuration file and change parameter value (see example in Figure 9) II Ensure that the primary supply voltage (e.g AC input) to the board is switched off and the hardware connection for configuration is ok based on Figure 2 and Figure 3. III Press to supply power and establish connection to the target XDPL8220. After this step, XDPL8220 will be in configuration mode and the device status should change to. IV Ensure LED output is connected to the board and switch on AC input (e.g. 230VAC). After this step, the board does not startup because XDPL8220 is still in configuration mode. V Press to test configuration with target XDPL8220 After this step, the IC will automatically start up with the new configuration and you should see a pop up window like below: VI VII Press OK on the pop up window. Repeat the steps to test another configuration change. Otherwise, turn off the AC input and disconnect the programming cable from board connector. Note: If there is any error encountered in between step I to VII, please kindly refer to the message bar of.dp Vision for the error message. For more details, please kindly refer to the.dp Vision user manual [5]. Application Note 11 Revision 1.0
