LM3503  
Dual-Display Constant Current LED Driver with Analog  
Brightness Control  
>
n
80% Peak Efficiency  
General Description  
n Output Voltage Protection Options: 16V, 25V, 35V & 44V  
n Input Under-Voltage Protection  
n Internal Soft Start Eliminates Inrush Current  
n 1 MHz Constant-Switching Frequency  
n Analog Brightness Control  
The LM3503 is a white LED driver for lighting applications.  
For dual display backlighting applications, the LM3503 pro-  
vides a complete solution. The LM3503 contains two internal  
white LED current bypass FET (Field Effect Transistor)  
switches. The white LED current can be adjusted with a DC  
voltage from a digital to analog converter or RC filtered PWM  
(pulse-width-modulated) signal at the Cntrl pin.  
n Wide Input Voltage Range: 2.5V to 5.5V  
n Low Profile Packages: 1 mm Height  
<
— 10 Bump MicroSMD  
— 16 Pin LLP  
With no external compensation, cycle-by-cycle current limit,  
output over-voltage protection, input under-voltage protec-  
tion, and dynamic white LED current control capability, the  
LM3503 offers superior performance over other step-up  
white LED drivers.  
Applications  
n Dual-Display Display Backlighting in Portable devices  
n Cellular Phones and PDAs  
Features  
n Drives up to 4, 6, 8 or 10 White LEDs for Dual Display  
Backlighting
