2.54mm PMIC TDA4605 8 Pin 8-DIP (0.300, 7.62mm)
The IC TDA 4605-1 controls the MOS-power 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 applicable tor consumer and industrial power supplies.
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. By varying switchon 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 ot 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.
TDA4605 Features
Fold-back characteristic provides overload protection for external components
Burst operation under short-circuit conditions
Loop error protection
Switch-off if line voltage is too low (undervoltage switch-off)
Line voltage compensation of overload point
Soft-start for quiet start-up
Chip-over temperature protection (thermal shutdown)
On-chip parasitic transformer oscillation suppression circuitry
TDA4605 Applications
5G communication,
automotive electrification,
industry 4.0
Advanced driver assistance systems (ADAS)
Body electronics & lighting
Hybrid, electric & powertrain systems
