The LM3492 demonstration board included in this package is designed for converting nominal 12VAC from electronic transformer output to drive seven series connected LEDs at 360- mA average current. The end user can directly light up a LED string through the demonstration board from an electronic transformer to test out the performance. With the demonstration board, the LED string not only runs at a constant current but also flicker free operation. The LM3492 switching frequency is set at a nominal 1MHz. This is a two layer board using the top layer for component placement and both layers for trace routing. A bill of materials below describes the parts used on the demonstration board. A schematic and layouts have also been included below. For detailed information regarding the LM3492 device, please refer to the LM3492 data sheet.
