General description
The TEA1761T is a member of the new generation of Synchronous Rectier (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 TEA1761T is a controller IC dedicated for synchronous rectication on the secondary
side of discontinuous conduction mode and quasi resonant yback converters. Besides
electronics for synchronous rectication, it also has integrated circuitry for output voltage
and output current regulation.
The TEA1761T is fabricated in a Silicon On Insulator (SOI) process. This NXP SOI
process makes possible a wide range of operation.

Features
2.1 Distinctive features
I Combined synchronous rectication and primary feedback control functionality
I Wide supply voltage range (8.6 V to 38 V)
I High level of integration, resulting in a very low external component count
I Wide opto coupler output voltage range (3.5 V to 38 V)
I Accurate internal voltage reference for voltage control (within 1 %)
I High driver output voltage of 10 V to drive all MOSFET brands to the lowest RDSon
2.2 Green features
I Low current consumption
I High system efciency from no load to full load
2.3 Protection features
I Undervoltage protection
I Internal over-temperature protection
3.
Applications
The TEA1761T is intended for adapters. The device can also be used in all other
discontinuous conduction mode and quasi resonant yback systems that demand a highly
efcient and cost-effective solution.
