TEA1792T

TEA1792T 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.
