Synchronous rectification controller suitable for both high-side and low-side control

Overview

The TEA1792T is a member of the new generation of Synchronous Rectifier (SR) controller ICs for switched mode power supplies. Its high level of integration allows the design of a cost-effective power supply with a very low number of external components. The TEA1792T is a controller IC dedicated to synchronous rectification on the secondary side of discontinuous conduction mode and quasi-resonant flyback converters. The TEA1792T is fabricated in a Silicon-On-Insulator (SOI) process.

Features

Accurate synchronous rectification functionality
Wide supply voltage range (8.5 V to 38 V)
High level of integration, resulting in a very low external component count
High driver output voltage of 10 V to drive all MOSFET brands to the lowest RDSon
Selectable regulation level for driver stage
Low current consumption
High system efficiency from no load to full load
Undervoltage protection

Target Applications

Intended for adapters and other discontinuous conduction mode systems
