XDPL8218 design guide
For high power factor flyback converter with constant voltage output
Parameter configuration list, set-up and procedures
There are two options available to configure the IC based on the list of parameter values shown in .dp Vision.

Burn configuration
It is important to note that the new XDPL8218 chip from Infineon does not contain any parameter
configuration by default, so the user should first burn a full set of parameters on the new chip using this
function, before any application testing. If the XDPL8218 chip on board has already been burned with a
first full set of parameters in its One-Time Programmable (OTP) memory space, such as the XDPL8218
40 W reference board, any IC parameter value change on it with this option is considered as parameter
patching. There are total 77 patchable OTP memory spaces.
Each time the burn configuration function is executed, .dp Vision will detect if there is parameter value
difference between the saved configuration file and the target XDPL8218. If a difference is detected,
each burn configuration will consume a minimum of three patchable memory spaces. However, the
process will be aborted if it requires more memory space than what is available on the target IC. In that
case, the user will have to replace the XDPL8218 chip with a new one in order to burn the configuration.
Table 11 shows the recommended procedures for using the burn configuration function in .dp Vision to
burn a first full set of parameters or patch the parameters into the OTP memory.
Table 11 Burn configuration procedures
Step Instruction
I Open configuration file using .dp Vision (see example in Figure 23 ).
II If necessary, change any parameter value (see example in Figure 24 ), then click [File] >>
[Save] or [File] >> [Save as] to save the configuration file. Otherwise, proceed to step III.
III Ensure that the primary supply voltages (e.g. AC input) to the board are switched off or
disconnected, and the hardware connection for configuration is OK based on
Figure 22 .
IV
Click to supply power and establish a connection to the target XDPL8218. After this
step, XDPL8218 will be in configuration mode (with V
CC
voltage for OTP programming at
7.5 V ± 0.15 V) and the device status should change to .
V
Click to burn the configuration to the target XDPL8218.
After this step, you should see a pop-up window, which is similar to one of those below.
VI Click “Proceed” or “Yes” to burn/patch the configuration.
After this step, a pop-up window should show that the burning/patching is successful.
VII Click “OK” on the pop-up window, then disconnect the programming cable from the
XDPL8218 configuration connector and test the application, if needed.
