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
