TEA1892: GreenChip synchronous rectifier controller

Overview

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.

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
Low current consumption
High system efficiency from no-load to full load
UnderVoltage Protection (UVP)

Target 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.
