LM3502

Step-Up Converter for White LED Applications

General Description

Features

n Drive up to 4, 6, 8 or 10 white LEDs for Dual Display

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 whitle LED current bypass

FET(Field Effect Transitor) switches that are ideal for con-

troling dual display applications. The while LED current can

be adjusted with a PWM signal directly from a microcontrol-

ler without the need of an RC filter network.

Backlighting

80% efficiency

n Output Voltage Options: 16V , 25V , 35V, and 44V

n Input Under-Voltage Protection

n Internal Soft Start Eliminating Inrush Current

n 1 MHz Constant-Switching Frequency

n Wide Input Voltage: 2.5V to 5.5V

n Small External Components

n Low Profile Packages: 1 mm Height

-10 Bump MicroSMD

-16 Pin LLP

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.

Applications

n Dual Display BackLighting in Portable Devices

n Cellular Phones and PDAs

Typical Application
