I would like to know the possibilities of LLC topology in charger applications.
In the whitepaper at the following URL, there is a description of the main LLC position, but it is not mentioned in the topology comparison in Table 1.
Can someone add LLC to this table?

Hi. Infineon
In my application; use 3172P to design in type-C adapter. now, the QC2.0 and QC3.0 OCP test data as below,230V AC input ,the QC2.0 and QC3.0 12V2.5A and 20V 1.5A OCP test result is 3.44A and 2.32A. I try to modify the battery.charging.h QC_AMP_20V(300 -->210 and 110) and QC_AMP_12V(300-->110 and 90) , but the test ressult without any change. would you like to let me know where to change to let the OCP meet customer requirement. and add schematic in here.
thanks

Applications for CCG3PA in the datasheet only show connections to Type-C Receptacles.
Final systems, where this application are used, will convert the Type-C Receptacle to a Type-C Plug via a USB-C cable. The cable adds a pulldown resistor, Ra, of about 1k ohm and possibly a, EMCA device. If connecting a CCG3PA directly to a Type-C Plug, one CC line can be tied via 1k ohm to ground to provide symmetry. Are any other changes required from the basic design in Figure 8 of the CCG3PA datasheet?
Is the EMCA functionality needed if the physical cable isn't present?
What else is missing? Will CCG3PA software support the "Plug" configuration shown below?
