LM3444 230VAC, 8W Isolated Flyback LED Driver Demo Board Schematic
WARNING
The
LM3444
evaluation
board
has
exposed
high
voltage
components that present a shock hazard. Caution must be taken
when handling the evaluation board. Avoid touching the evaluation
board and removing any cables while the evaluation board is
operating.
when handling the evaluation board. Avoid touching the evaluation
board and removing any cables while the evaluation board is
operating.
WARNING
The ground connection on the evaluation board is NOT referenced
to earth ground. If an oscilloscope ground lead is connected to the
evaluation board ground test point for analysis and the mains AC
power is applied (without any isolation), the fuse (F1) will fail open.
For bench evaluation, either the input AC power source or the
bench measurement equipment should be isolated from the earth
ground connection. Isolating the evaluation board (using 1:1 line
isolation transformer) rather than the oscilloscope is highly
recommended.

The LM3444 evaluation board should not be powered with an open
load. For proper operation, ensure that the desired number of LEDs
are connected at the output before applying power to the
evaluation board.
