... Suppression Circuitry Decrease of Regulated Voltage for low Power Consumption DESCRIPTION The IC TDA4605 controls the MOS Power Tran- sistor and performs all necessary regulation and monitoring functions in free running flyback con- verters. Since good load regulation over a wide load range is attained, this IC is particularly suita- ble for Consumer as well as Industrial Power Sup- plies ...

... FUNCTIONAL DESCRIPTION In free running fly-back converters, the TDA4605 assumes control of a MOS power transistor and all necessary regulation and monitoring functions. The serial circuit of power transistor and primary winding of the flyback transformer is connected to the input voltage. During the switch-on period of the transistor, energy is stored in the transformer and during the switch-off period it is fed to the load via the secondary winding ...
