TEA1791T

TEA1791T GreenChip synchronous rectifier controller Rev. 02 — 7 June 2010 Product data sheet 1. General description 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. 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 2.2 Green features „ Low current consumption „ High system efficiency from no load to full load 2.3 Protection features „ Undervoltage protection 3. Applications „ The TEA1791T 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. 4.
