NATIONAL SEMICONDUCTOR LM3502 Manual

Update: 29 September, 2023

LM3502 is a white LED driver for lighting applications. It provides a complete solution for dual display or large single white LED string backlighting applications. The LM3502 includes two internal white LED current bypass FET 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 for an RC filter network. With features such as no external compensation, cycle-by-cycle current limit, over-voltage protection, and under-voltage protection, the LM3502 offers superior performance compared to other application specific standard product step-up white LED drivers.
