3 Description  
Programmable Soft Start  
The LM3492/-Q1 integrates a boost converter and a  
two-channel current regulator to implement a high  
efficient and cost effective LED driver for driving two  
individually dimmable LED strings with a maximum  
power of 15 W and an output voltage of up to 65 V.  
The boost converter employs a proprietary Projected-  
On-Time control method to give a fast transient  
response with no compensation required, and a  
nearly constant switching frequency programmable  
from 200 kHz to 1 MHz. The application circuit is  
stable with ceramic capacitors and produces no  
audible noise on dimming. The programmable peak  
current limit and soft-start features reduce current  
surges at start-up, and an integrated 190 mΩ, 3.9-A  
N-Channel MOSFET switch minimizes the solution  
size.  
No Loop Compensation Required  
Stable With Ceramic and Other Low ESR  
Capacitors With No Audible Noise  
Nearly Constant Switching Frequency  
Programmable From 200 kHz to 1 MHz  
Current Regulators:  
Programmable LED Current from 50 mA to  
200 mA  
1000:1 Contrast Ratio at a Dimming  
Frequency of More Than 3 kHz, Minimum LED  
Current Pulse Width is 300 ns  
Two Individual Dimmable LED Strings up to  
65 V, Total 15 W (Typically 28 LEDs at  
150 mA)
