Overview

com LM3503 Dual-Display Constant Current LED Driver with Analog Brightness Control July 2005 LM3503 Dual-Display Constant Current LED Driver with Analog Brightness Control General Description The LM3503 is a white LED driver for lighting applications.
For dual display backlighting applications, the LM3503 provides 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.
With no external compensation, cycle-by-cycle current limit, output over-voltage protec...
