GreenChip synchronous rectifier controller
Rev. 2 — 9 July 2012
Product data sheet
1. General description
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.
2. Features and benefits
2.1 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
2.2 Green features
Low current consumption
High system efficiency from no load to full load
2.3 Protection features
UnderVoltage Protection (UVP)
3. Applications
The TEA1792T 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.
