LM3424-Q1  
SNVSB96 JULY 2019  
LM3424-Q1 Constant Current N-channel Controller  
with Thermal Foldback For Driving LEDs  
1 Features  
3 Description  
The LM3424-Q1 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. In addition, the LM3424-Q1 includes a  
1
AEC Qualified for automotive applications  
Device temperature grade 1: 40°C TA ≤  
125°C  
VIN range from 4.5 V to 75 V  
thermal  
foldback  
feature  
for  
temperature  
management of the LEDs. This flexibility, along with  
an input voltage rating of 75 V, makes the LM3424-  
Q1 ideal for illuminating LEDs in a large family of  
applications.  
High-side adjustable current sense  
2-, 1-A peak MOSFET gate driver  
Input undervoltage and output overvoltage  
protection  
Adjustable high-side current sense allows for tight  
regulation of the LED current with the highest  
efficiency possible. The LM3424-Q1 uses standard  
peak current-mode control providing inherent input  
voltage feed-forward compensation for better noise  
immunity. It is designed to provide accurate thermal  
foldback with a programmable foldback breakpoint  
and slope. In addition, a 2.45V reference is provided.  
PWM and analog dimming  
Cycle-by-cycle current limit  
Programmable soft-start and slope compensation  
Programmable, synchronizable switching  
frequency  
Programmable thermal foldback  
Precision voltage reference  
The LM3424-Q1 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 2.0 MHz  
and external synchronization is possible. The  
controller is capable of high speed PWM dimming  
and analog dimming.  
Low-power shutdown and thermal shutdown
