TDA4605-3 Control IC for Switched-Mode Power Supplies using MOS-Transistor Infineon Technologies

Features
l Fold-back characteristics provides overload protection for
external components
l Burst operation under secondary short-circuit condition
implemented
l Protection against open or a short of the control loop
l Switch-off if line voltage is too low (undervoltage switch-off)
l Line voltage depending compensation of fold-back point
l Soft-start for quiet start-up without noise generated by the
transformer
l Chip-over temperature protection implemented (thermal
shutdown)
l On-chip ringing suppression circuit against parasitic
oscillations of the transformer
l AGC-voltage reduction at low load
