Overview
The TEA19162T/1J, produced by NXP USA Inc., is a Power Factor Correction (PFC) controller IC designed for resonant topologies. It is part of a combined controller (combo) IC set that includes the TEA19161T LLC resonant controller. Together, these ICs enable the creation of highly efficient and reliable power supplies that comply with various efficiency regulations such as Energy Star, the Department of Energy (DoE), and the Eco-design Directive of the European Union. The TEA19162T communicates with the TEA19161T on start-up sequences and protections, and it supports a fast latch reset mechanism to enhance system efficiency.
