OR:  

The TEA1792T 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 TEA1792T is a controller IC dedicated to synchronous rectification on the secondary side of discontinuous conduction mode and quasi-resonant flyback converters. The TEA1792T is fabricated in a Silicon-On-Insulator (SOI) process.

Features and benefits

  • 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

Applications

  • Intended for adapters and other discontinuous conduction mode systems
