1 General description
The TEA1993TS is a member of a new generation of Synchronous Rectifier (SR)
controller ICs for switched mode power supplies. It includes an adaptive gate drive for
maximum efficiency at any load.
The TEA1993TS is a dedicated controller IC for synchronous rectification on the
secondary side of flyback converters. It incorporates the sensing stage and driver stage
for driving the SR MOSFET, which is rectifying the output of the secondary transformer
winding.
The TEA1993TS can generate its own supply voltage for battery charging applications
with low output voltage or for applications with high-side rectification.
The TEA1993TS is fabricated in a Silicon-On-Insulator (SOI) process.

3 Applications
The TEA1993TS 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 needing high efficiency, like:
Chargers
Adapters
Flyback power supplies with very low and/or variable output voltage
