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

The TEA1892TS is fabricated in a Silicon-On-Insulator (SOI) process.

• 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
• Low current consumption
• High system efficiency from no-load to full load
• UnderVoltage Protection (UVP)

• The TEA1892TS is intended for adapters. The device can also be used in all otherdiscontinuous conduction mode systems and quasi-resonant flyback systems thatdemand a highly efficient and cost-effective solution.
