DESCRIPTION
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 white LED
current bypass FET(Field Effect Transistor) switches that are ideal for controlling dual display applications. The
white LED current can be adjusted with a PWM signal directly from a microcontroller without the need of an RC
filter network.
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.
