LM3414SDX National Semiconductor Corporation, LM3414SDX Datasheet - Page 7

• 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

Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the
device is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: The human body model is a 100pF capacitor discharged through a 1.5 kΩ resistor into each pin.
Note 3: Tested on a 4 layer JEDEC board. Four vias provided under the exposed pad. See JESD51-5 and JESD51-7. The value of the θ
is specifically dependent on the PCB trace area, trace material, and the number of layers and thermal vias. For improved thermal resistance and power dissipation
for the LLP package, refer to Application Note AN-1187.
Note 4: Typical specification represent the most likely parametric norm at 25°C operation.
Note 5: VCC provides self bias for the internal gate drive and control circuits. Device thermal limitations limit external loading to the pin.
