LM3502  
Step-Up Converter for White LED Applications  
General Description  
Features  
n Drive up to 4, 6, 8 or 10 white LEDs for Dual Display  
The LM3502 is a white LED driver for lighting applications.  
For dual display or large single white LED string backlighting  
applications, the LM3502 provides a complete solution. The  
LM3502 contains two internal whitle LED current bypass  
FET(Field Effect Transitor) switches that are ideal for con-  
troling dual display applications. The while LED current can  
be adjusted with a PWM signal directly from a microcontrol-  
ler without the need of an RC filter network.

n
80% efficiency  
n Output Voltage Options: 16V , 25V , 35V, and 44V  
n Input Under-Voltage Protection  
n Internal Soft Start Eliminating Inrush Current  
n 1 MHz Constant-Switching Frequency  
n Wide Input Voltage: 2.5V to 5.5V  
n Small External Components  
n Low Profile Packages: 1 mm Height  
-10 Bump MicroSMD  
-16 Pin LLP  
With no external compensation, cycle-by-cycle current limit,  
over-voltage protection, and under-voltage protection, the  
LM3502 offers superior performance over other application  
specific standard product step-up white LED drivers.
