Product Summary

The IC TDA4605 controls theMOSPower Transistor and performs all necessary regulation and monitoring functions in free running flyback converters. Since good load regulation over a wide load range is attained, this IC is particularly suitable for Consumeras well as IndustrialPower Supplies. Alternative source of the TDA4605 is also available from SIEMENS Semiconductors Consumer Electronics A.G.
