NXP Semiconductors TEA2096

TEA2096T new Synchronous Rectifier controller IC for switched-mode power supplies. It incorporates an adaptive gate drive method for maximum efficiency at any load.

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. Optimized for efficient operation with very low-ohmic MOSFETs and switching at high frequencies. The TEA2096T is fabricated in a silicon-on-insulator (SOI) process.
