SLUAAB9A March 2021 – December 2021 UCC25800-Q1
To simplify the design process, different transformer vendors have designed and released stardard LLC transformers for the isolated bias supply applications. In Table 5-2 , there is a summarized set of transformers that can be used together with UCC25800-Q1 for the typical input and output voltage for different applications. This list is not exhaustive and there are many other standard transformers that work for this type of application.
