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
