LM3429  
N-Channel Controller for Constant Current LED Drivers  
General Description  
Features  
The LM3429 is a versatile high voltage N-channel MosFET  
controller for LED drivers . It can be easily configured in buck,  
boost, buck-boost and SEPIC topologies. This flexibility,  
along with an input voltage rating of 75V, makes the LM3429  
ideal for illuminating LEDs in a very diverse, large family of  
applications.  
VIN range from 4.5V to 75V  
Adjustable current sense voltage  
High-side current sensing  
2Ω, 1A Peak MosFET gate driver  
Input under-voltage protection  
Over-voltage protection  
PWM dimming  
Adjustable high-side current sense voltage allows for tight  
regulation of the LED current with the highest efficiency pos-  
sible. The LM3429 uses Predictive Off-time (PRO) control,  
which is a combination of peak current-mode control and a  
predictive off-timer. This method of control eases the design  
of loop compensation while providing inherent input voltage  
feed-forward compensation.  
Analog dimming  
Cycle-by-cycle current limit  
Programmable switching frequency  
Thermal Shutdown  
The LM3429 includes a high-voltage startup regulator that  
operates over a wide input range of 4.5V to 75V. The internal  
PWM controller is designed for adjustable switching frequen-  
cies of up to 2.0 MHz, thus enabling compact solutions.  
Additional features include analog dimming, PWM dimming,  
over-voltage protection, under-voltage lock-out, cycle-by-cy-  
cle current limit, and thermal shutdown.
