The TEA2017AAT 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
enables building a complete resonant power supply which is easy to design and has a very low component count. The TEA2017AAT comes in a low profile and narrow body-width SO16
The TEA2017AAT digital architecture is based on a high-speed configurable hardware state machine ensuring very reliable real-time performance. During the power supply
development, many operation and protection settings of the LLC and PFC controller can be adjusted by loading new settings into the device to meet specific application
requirements. The configurations can be fully secured to prevent unauthorized copying of the proprietary TEA2017AAT configuration content.
In contrast to traditional resonant topologies, the TEA2017AAT shows a very high efficiency at low loads due to the LLC low-power mode. This mode operates in the power region
between continuous switching (also called high-power mode) and burst mode.
