Optimized for Lowest System Cost ? Proprietary IC trimming and transformer construction techniques enable Clampless? designs with LNK362 for lower system cost， component count and higher effi ciency ? Fully integrated auto-restart for short circuit and open loop protection ? Self-biased supply – saves transformer auxiliary winding and associated bias supply components ? Frequency jittering greatly reduces EMI ? Meets HV creepage requirements between DRAIN and all other pins both on the PCB and at the package ? Lowest component count switcher solution Features Superior to Linear/RCC ? Accurate hysteretic thermal shutdown protection – automatic recovery improves fi eld reliability ? Universal input range allows worldwide operation ? Simple ON/OFF control， no loop compensation needed ? Eliminates bias winding – simpler， lower cost transformer ? Very low component count – higher reliability and single side printed circuit board ? Auto-restart reduces delivered power by 95% during short circuit and open loop fault conditions ? High bandwidth provides fast turn-on with no overshoot and excellent transient load response
