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
