TEA1761T
Datasheet
General description
The TEA1761T 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 TEA1761T is a controller IC dedicated for synchronous rectification on the secondary side of discontinuous conduction mode and quasi resonant flyback converters. Besides electronics for synchronous rectification, 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
Distinctive features
- Combined synchronous rectification and primary feedback control functionality
- Wide supply voltage range (8.6 V to 38 V)
- High level of integration, resulting in a very low external component count
- Wide opto coupler output voltage range (3.5 V to 38 V)
- Accurate internal voltage reference for voltage control (within 1 pct)
- High driver output voltage of 10 V to drive all MOSFET brands to the lowest RDSon
Green features
- Low current consumption
- High system efficiency from no load to full load
Protection features
- Undervoltage protection
- Internal over-temperature protection
