LM3429, LM3429-Q1  
SNVS616H APRIL 2009REVISED JULY 2015  
LM3429/-Q1 N-Channel Controller for Constant Current LED Drivers  
1 Features  
3 Description  
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.  
1
LM3429-Q1 is AEC-Q100 Grade 1 Qualified for  
Automotive Applications  
VIN Range From 4.5 V to 75 V  
Adjustable Current Sense Voltage  
High-Side Current Sensing  
2-, 1-A Peak MosFET Gate Driver  
Input Undervoltage Protection  
Overvoltage Protection  
Adjustable high-side current sense voltage allows for  
tight regulation of the LED current with the highest  
efficiency possible. 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.  
PWM Dimming  
Analog Dimming  
Cycle-by-Cycle Current Limit  
Programmable Switching Frequency  
Low Profile 14-lead HTSSOP Package  
Thermal Shutdown  
The LM3429 includes a high-voltage startup regulator  
that operates over a wide input range of 4.5 V to 75  
V. The internal PWM controller is designed for  
adjustable switching frequencies of up to 2 MHz, thus  
enabling compact solutions. Additional features  
include analog dimming, PWM dimming, overvoltage  
protection, undervoltage lock-out, cycle-by-cycle  
current limit, and thermal shutdown.
