TDA4605-3

Control IC for Switched-Mode Power Supplies

using MOS-Transistor

Fold-back characteristic 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 transformar

Chip-over temperature protection implement (thermal

shutdown)

One-chip ringing suppression circuit against parasitic

oscillations of the transformer

AGC-voltage reduction at low load
