LM3445 ? 220VAC, 7W Dimmable Isolated (PMP7751)

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.
