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 AC power is

applied, the fuse (F1) will fail open. The oscilloscope should be

powered via an isolation transformer before an oscilloscope

ground lead is connected to the evaluation board.

WARNING

The LM3448 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.
