♠ GreenChip dual synchronous rectifier controller
The TEA1995T is the first product of a new generation of Synchronous Rectifier (SR) controller ICs for switched mode power supplies. It incorporates an adaptive gate drive method 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 rectify the outputs of the central tap secondary transformer windings. The two gate driver stages have their own sensing inputs and operate independently.
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.
