LM3401  
Hysteretic PFET Controller for High Power LED Drive  
General Description  
Features  
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. Out-  
put current is adjusted with an external current sensing resis-  
tor 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 pro-  
tection against over current and short circuit failures. Addi-  
tional features include adjustable hysteresis and a CMOS  
compatible input pin for PWM dimming.  
Adjustable hysteresis  
Input UVLO  
No output capacitor required
