Overview
The TEA1998TS/1X, produced by NXP USA Inc., is a dedicated controller IC for synchronous rectification on the secondary side of flyback converters. This GreenChip synchronous rectifier controller is designed to enhance efficiency in switched mode power supplies (SMPS) by using adaptive gate drive technology. Fabricated in a Silicon-On-Insulator (SOI) process, it integrates both the sensing stage and driver stage for driving the synchronous rectifier (SR) MOSFET, which replaces the traditional diode for rectification of the output voltage on the secondary transformer winding.
