220V Triac Dimmable Off-line LED Driver Evaluation Board
LM3445 Product Folder Description:
The LM3445 220V Off-Line TRIAC Dimmer LED board is optimized to convert 190VAC to 265VAC input (will work down to 90V), and drives seven, or eight series connected LEDs at 400 mA average current. The LM3445 switching frequency is set at a nominal 100 kHz. This is a two-layer board using both the bottom and top layer for component placement. The demonstration board can be modified to adjust the LED forward current, the number of series connected LEDs and switching frequency.
