100V and Above Output Voltages Posted by: aliaykan on Mon, 11/12/2012 Hi, I need to implement 100V and above output Constant Current Led Drivers. But PI Expert doesn't allow voltages more than 100V. Is it possible? Thanks for your helps. 评论 It is recommended to use PIXL for LED driver design software, and there is no issue with higher than 100 V output design with either LNKPL or LNKPH. Updated PI Export with LED driver application will be available in the near future. There are three reference designs in the Design Support, DER 287, DER298, DER324, for higher than 100 V output LED driver with constant current.
