Product Summary
The TEA1761T is a Synchronous Rectifier (SR) controller IC 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.
Parametrics
TEA1761T absolute maximum ratings: (1)supply voltage: -0.4 to +38 V; (2)voltage on pin OPTO: -0.4 to +38 V; (3)voltage on pin SRSENSE: 120 V; (4)voltage on pin VSENSE: -0.4 to +5 V; (5)voltage on pin ISENSE: -0.4 to +5 V; (6)current on pin: 12 mA; (7)current on pin DRIVER: -0.8 to +3 A; (8)current on pin SRSENSE: -3 mA; (9)total power dissipation: 0.45 W; (10)storage temperature: -55 to +150 ℃; (11)junction temperature: -20 to +150 ℃.
Features
TEA1761T features: (1)Combined synchronous rectification and primary feedback control functionality; (2)Wide supply voltage range (8.6 V to 38 V); (3)High level of integration, resulting in a very low external component count; (4)Wide opto coupler output voltage range (3.5 V to 38 V); (5)Accurate internal voltage reference for voltage control (within 1 %); (6)High driver output voltage of 10 V to drive all MOSFET brands to the lowest RDSon.
