描述 Description

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.
The TEA1995T is intended for resonant power supplies. In such applications, it can drive two external Synchronous Rectifier MOSFETs which replace diodes for the rectification of the voltages on the two secondary windings of the transformer. It can be used in all power supplies needing high-efficiency.
