RDR-131 LED Driver – LNK306DN
1 Introduction
This engineering report describes an LED driver power supply that uses a member of
the LinkSwitch-TN family of devices, the LNK306DN. The circuit regulates its load
current to 300 mA while developing about 10 V across three series HB-LEDs.
The design provides no safety isolation between the AC input and DC output. Therefore
the enclosure must be designed to provide isolation.
The report contains the power supply specification, a circuit diagram, a complete bill of
materials, the PI Xls spreadsheet results for the design, the printed circuit board
layouts, and performance data.
