TEA1998TS: GreenChip synchronous rectifier controller

Overview

SOT457

SOT457

Features

Target Applications

The TEA1998TS is intended for flyback power supplies. In such applications, it can drive the external synchronous rectifier MOSFET, which replaces the diode for the rectification of the voltage on the secondary winding of the transformer.

It can be used in all power supplies that require a high efficiency, like:

  • Chargers
  • Adapters
  • Flyback power supplies with very low and/or variable output voltage
