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

Power MOSFET
●VDS= 600 V
●RDS ON= 3.0Ω
●Repetitive Avalanche
