Synchronous Rectifier Controller 8-Pin SO T/R

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.

• 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
• Low current consumption
• High system efficiency from no load to full load
• Undervoltage protection
