General description
The TEA1795T is a member of the new generation of Synchronous Rectifier (SR)
controller ICs for switched mode power supplies. Its high level of integration enables the
design of a cost-effective power supply with a minimum number of external components.
The TEA1795T is 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
are rectifying the outputs of the central tap secondary transformer windings.
The two gate driver stages have their own sensing inputs and operate independently of
each other.
The TEA1795T is fabricated in a Silicon On Insulator (SOI) process.

Features and benefits
2.1 Distinctive features
Accurate synchronous rectification functionality
Wide supply voltage range (8.5 V to 38 V)
Separate sense inputs for sensing the drain and source voltage of each SR MOSFET
High level of integration, resulting in a minimum external component count
High driver output voltage of 10 V to drive all MOSFET brands to the lowest RDSon
2.2 Green features
Low current consumption
High system efficiency from no load to full load
2.3 Protection features
UnderVoltage Protection (UVP)
3.
Applications
The TEA1795T is intended for resonant power supplies. In such applications, it can drive
two external synchronous rectifier MOSFETs which replace diodes for the rectification of
the voltages on the two secondary windings of the transformer. It can be used in
applications such as:
Adapters
ATX power supplies
