High efficient and cost-effective solution.


The TEA1761 is a member of the new generation of synchronous rectifier 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 TEA1761 is a controller IC dedicated for synchronous rectification on the secondary side of discontinuous conduction mode and quasi resonant flyback converters. Besides electronics for synchronous rectification, also circuitry for output voltage and output current regulation is integrated.
