... Si9118/Si9119 Vishay Siliconix DETAILED OPERATIONAL DESCRIPTION Start-Up Si9118/Si9119 are designed with internal depletion mode MOSFET capable of powering directly from the high input bus voltage. This feature eliminates the typ- ical external start-up circuit saving valuable space and cost. But, most of all, this feature improves the con- verter efficiency during full load and has an even greater impact on light load ...
