FEATURES  
DESCRIPTION  
The LM3401 is a switching controller designed to  
provide constant current to high power LEDs. The  
LM3401 drives an external P-MOSFET switch for  
step-down (Buck) regulators. The LM3401 delivers  
constant current within ±6% accuracy to a wide  
variety and number of series connected LEDs. Output  
current is adjusted with an external current sensing  
resistor to drive high power LEDs in excess of 1A.

Hysteretic Control for Speed and Simplicity  
Input Operating Range of 4.5V-35V  
1.5MHz Maximum Switching Frequency  
Low 200mV Reference Voltage  
Programmable Current Limit  
High speed CMOS Compatible  
Enable/Dimming  
For improved accuracy and efficiency, the LM3401  
features dual-side hysteresis, very low reference  
voltage, and short propagation delay. A cycle by  
cycle current limit provides protection against over  
current and short circuit failures. Additional features  
Adjustable Hysteresis  
Input UVLO  
No output Capacitor Required  
8-pin VSSOP Package  
include adjustable hysteresis and  
compatible input pin for PWM dimming.
