This demonstration board highlights the performance of a LM3445 based Flyback LED driver solution that can be used to power a single LED string consisting of 6 / 7 series connected LEDs from an 198 VRMS to 264 VRMS: 50 Hz input power supply. This is a two-layer board using 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 that are driven and the switching frequency. Refer to the LM3445 datasheet for detailed instructions. A bill of materials is included that describes the parts used on this demonstration board.
