DER-47, 2W Non-isolated Power Supply using LNK305P

DER-47, Reference Design shows 15V, 130mA non-isolated power supply using a LNK305P.The tested power supply had an input stage including one diode for the rectification and a p filter (4.7uF, 1mH, 4.7uF), but this stage is not included in the schematic, and may not be needed in other systems if EMI filtering is present
