LM3414SDX National Semiconductor Corporation, LM3414SDX Datasheet - Page 15

• Manufacturer Part Number: LM3414SDX
• Description: Lm3414/lm3414hv 1a 60w* Common Anode Capable Constant Current Buck Led Driver Requires No External Current Sensing Resistor
• Manufacturer: National Semiconductor Corporation

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.
