Control IC for Switched-Mode Power Supplies  
using MOS-Transistors  
TDA 4605-2  
Bipolar IC  
Features  
● Fold-back characteristics provides overload protection for  
external components  
● Burst operation under secondary short-circuit condition  
implemented  
● Protection against open or a short of the control loop  
● Switch-off if line voltage is too low (undervoltage switch-off)  
● Line voltage depending compensation of fold-back point  
● Soft-start for quiet start-up without noise generated by the  
transformer  
P-DIP-8-1  
● Chip-over temperature protection implemented (thermal  
shutdown)  
● On-chip ringing suppression circuit against parasitic  
oscillations of the transformer

Package  
TDA 4605-2  
Q67000-A5020  
P-DIP-8-1  
The IC TDA 4605-2 controls the MOS-power transistor and performs all necessary regulation and  
monitoring functions in free running flyback converters. Because of the fact that a wide load range  
is achieved, this IC is applicable for consumer as well as industrial power supplies.  
The serial circuit and primary winding of the flyback transformer are connected in series to the input  
voltage. During the switch-on period of the transistor, energy is stored in the transformer. During the  
switch-off period the energy is fed to the load via the secondary winding. By varying switch-on time  
of the power transistor, the IC controls each portion of energy transferred to the secondary side  
such that the output voltage remains nearly independent of load variations. The required control  
information is taken from the input voltage during the switch-on period and from a regulation winding  
during the switch-off period. A new cycle will start if the transformer has transferred the stored  
energy completely into the load.
