LM342x-Q1 N -Channel Controllers for Constant-Current LED Drivers  
1 Features  
3 Description  
The LM3421-Q1 and LM3423-Q1 family of devices  
are versatile high voltage N-channel MOSFET  
controllers for LED drivers. They can be easily  
configured in buck, boost, buck-boost and SEPIC  
topologies. This flexibility, along with an input voltage  
rating of 75 V, makes the these controllers ideal for  
illuminating LEDs in a large family of applications.

AEC Qualified for Automotive Applications  
Device Temperature Grade 1: 40°C TA ≤  
125°C (LM3421-Q1 and LM3423-Q1)  
Device Temperature Grade 0: 40°C TA ≤  
150°C (LM3421-Q0 and LM3423-Q0)  
VIN Range From 4.5 V to 75 V  
Adjustable high-side current sense voltage allows for  
tight regulation of the LED current with the highest  
efficiency possible. The LM3421-Q1 and LM3423-Q1  
devices use 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.  
High-Side Adjustable Current Sense  
2-, 1-A Peak MOSFET Gate Driver  
Input Undervoltage and Output Overvoltage  
Protection  
PWM and Analog Dimming  
Cycle-by-Cycle Current Limit  
Programmable Switching Frequency  
Zero Current Shutdown and Thermal Shutdown  
The LM3421-Q1 and LM3423-Q1 devices include a  
high-voltage start-up 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.
