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
● Chip-over temperature protection implemented (thermal shutdown)
● On-chip ringing suppression circuit against parasitic oscillations of the transformer
