General description

The TEA1791T is a member of the new generation of Synchronous Rectifier (SR)

controller ICs for switched mode power supplies. Its high level of integration allows the

design of a cost-effective power supply with a very low number of external components.

The TEA1791T is a controller IC dedicated to synchronous rectification on the secondary

side of discontinuous conduction mode and quasi-resonant flyback converters.

The TEA1791T is fabricated in a Silicon On Insulator (SOI) process.
