TEA2096T/1J

TEA2096T/1J is a new synchronous rectifier (SR) controller IC for a switched-mode power supply. It incorporates an adaptive gate drive method for maximum efficiency at any load. This 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. It is optimized for efficient operation with very low-osmic MOSFETs and switching at high frequencies. This is fabricated in a silicon-on-insulator (SOI) process. Application includes Adapters, power supplies for desktop PC and all-in-one PC, power supplies for television, power supplies for servers, power supplies for industrial applications.
