FEATURES  
DESCRIPTION  
The LM3414 and LM3414HV are 1A 60W (see Note  
below) common anode capable constant current buck  
LED drivers. They are exceptionally suitable to drive  
single string of 3W HBLED with up to 96% efficiency.  
They accept input voltages from 4.5VDC to 65VDC  
and deliver up to 1A average LED current with ±3%  
accuracy. The integrated low-side N-channel power  
MOSFET and current sensing element realize simple  
and low component count circuitry as no  
bootstrapping capacitor and external current sensing  
resistor are required. An external small-signal resistor  
to ground provides very fine LED current adjustment,  
analog dimming as well as thermal fold-back  
functions.

Constant switching frequency operation eases EMI.  
No external loop compensation network is needed.  
The proprietary Pulse-Level-Modulation (PLM) control  
method benefits in high conversion efficiency and true  
average LED current regulation. Fast response time  
realizes fine LED current pulse fulfilling the 240 Hz  
256-step dimming resolution requirement for general  
lighting.
