Keywords:flyback? LED driver?

This demonstration board highlights the performance of a LM3444 based flyback LED driver solution that can be used to power a single LED string consisting of 4 to 10 series connected LEDs from an 180 VRMS to 265 VRMS, 50Hz input power supply. The key performance characteristics under typical operating conditions are summarized in this application note.

This is a four-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.
