TEA1995T - GreenChip Synchronous Rectifier controller - 次级侧控制器 - AC/DC转换器 - 恩智浦, LLC
The TEA1995T is the first product of a new generation of Synchronous Rectifier (SR) controller ICs for switched mode power supplies with adaptive gate drive for maximum efficiency at any load.
The TEA1995T is a dedicated controller IC for synchronous rectification on the secondary side of resonant converters. It has two driver stages for driving the SR MOSFETs which are rectifying the outputs of the secondary transformer windings. The two gate driver stages have their own sensing inputs and operate independently of each other.
The TEA1995T can also be used in multi-output flyback converters with the SR MOSFET placed at the low side.
The TEA1995T is fabricated in a Silicon On Insulator (SOI) process.
