Abstract 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,
circuitry for output voltage and output current regulation is integrated.
The TEA1761 is fabricated in a Silicon On Insulator (SOI) process. This
NXP SOI process makes a wide voltage range possible.
