TEA1892ATS GreenChip synchronous rectifier controller Rev. 1 10 April 2014 Product data sheet 1. General description The TEA1892ATS 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 TEA1892ATS is a controller IC dedicated to synchronous rectification on the secondary side of discontinuous conduction mode and quasi-resonant flyback converters. The TEA1892ATS 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 R DSon 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 TEA1892ATS 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.TEA1892ATS NXP Semiconductors GreenChip synchronous rectifier controller 4.
