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.
●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 %)
●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
●Applications
●The TEA1761T is intended for adapters. The device can also be used in all other discontinuous conduction mode and quasi resonant flyback systems that demand a highly efficient and cost-effective solution.
