LM3503SQ-44/NOPB

LED DRVR 10Segment 3.3V/5V 16Pin LLP EP T/R

The LM3503 is a white 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 protection, input under-voltage protection, and dynamic white LED current control capability, the LM3503 offers superior performance over other step-up white LED drivers.
