General description
The TEA1892TS 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 TEA1892TS is a controller IC dedicated to synchronous rectification on the secondary side of discontinuous conduction mode and quasi-resonant flyback converters.
The TEA1892TS is fabricated in a Silicon-On-Insulator (SOI) process.

FEATUREs and benefits
Distinctive features
■ Accurate synchronous rectification functionality
■ Wide supply voltage range (8.5 V to 38 V)
■ High level of integration, resulting in a very low external component count
■ High driver output voltage of 10 V to drive all MOSFET brands to the lowest RDSon
■ Selectable regulation level for driver stage

Green features
■ Low current consumption
■ High system efficiency from no-load to full load

Protection features
■ UnderVoltage Protection (UVP)

APPLICATIONs
■ The TEA1892TS is intended for adapters. The device can also be used in all other
   discontinuous conduction mode systems and quasi-resonant flyback systems that
   demand a highly efficient and cost-effective solution.
