The TEA2017AAT/3 is a digital configurable LLC and PFC combo controller for high efficiency resonant power supplies. It includes both the LLC controller and PFC controller functionality. The PFC can be configured to operate in DCM/QR, CCM fixed frequency or multimode which supports all operation modes to optimize the PFC efficiency. The TEA2017AAT/3 enables building a complete resonant power supply which is easy to design and has a very low component count. The difference of the TEA2017AAT/3 with respect to the TEA2017AAT/2 is that it has improved drivers and can start up faster to comply with the Intel ATX 3 specification. TEA2017DK1007 development kit includes a socket board for programming development samples in combination with the RDK01DB1563 I²C interface.
