LM3424  
SNVS603D AUGUST 2009REVISED JULY 2019  
LM3424 Constant Current N-channel Controller  
with Thermal Foldback For Driving LEDs  
1 Features  
3 Description  
The LM3424 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 includes  
1
VIN range from 4.5 V to 75 V  
High-side adjustable current sense  
2-, 1-A peak MOSFET gate driver  
a
thermal foldback feature for temperature  
Input undervoltage and output overvoltage  
protection  
management of the LEDs. This flexibility, along with  
an input voltage rating of 75 V, makes the LM3424  
ideal for illuminating LEDs in a large family of  
applications.  
PWM and analog dimming  
Cycle-by-cycle current limit  
Programmable soft-start and slope compensation  
Adjustable high-side current sense allows for tight  
regulation of the LED current with the highest  
efficiency possible. The LM3424 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.  
Programmable, synchronizable switching  
frequency  
Programmable thermal foldback  
Precision voltage reference  
Low-power shutdown and thermal shutdown  
2 Applications  
The LM3424 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.
