FIGURE 5. Shortened Current Slew up Time of the LM3414/14HV
To ensure normal operation of the LM3414/14HV, it is rec-
ommended to set the dimming frequency not higher than 1/10
of the switching frequency. The minimum dimming duty cycle
is limited by the 400 ns minimum ON time. In applications that
require high dimming contrast ratio, low dimming frequency
should be used.
