LM3533

Complete Lighting Power Solution for Smartphone Handsets

General Description

Features

The LM3533 is a complete power source for backlight, key-

pad, and indicator LEDs in smartphone handsets. The high-

voltage inductive boost converter provides the power for two

series LED strings for display backlight and keypad functions

(HVLED1 and HVLED2). The integrated charge pump pro-

vides the bias for the five low-voltage indicator LED current

sinks (LVLED1-LVLED5). All low-voltage current sinks can

have a programmable pattern modulated onto their output

current for a wide variety of blinking patterns.

Drives Two Parallel High-Voltage LED Strings for Display

and Keypad Lighting

●

High-Voltage Strings Capable of up to 40V Output Voltage

and up to 90% Efficiency

Up to 30mA per Current Sink (Both Backlight and

Indicator)

14-Bit Equivalent Exponential Dimming with 8-Bit

Programmable Backlight Code

Selectable Analog ALS Input with 128 Programmable Gain

Setting Resistors or PWM ALS Input with Internal Low

Pass Filter

Additional features include a Pulse Width Modulation (PWM)

control input for content adjustable backlight control, and an

Ambient Light Sensor interface (ALS) with an internal 8-bit

ADC to provide automatic current adjustment based upon

ambient light conditions. Both the PWM and ALS inputs can

be used to control any high- or low-voltage current sink.

The LM3533 is fully programmable via an I²C-compatible in-

terface. The device is available in a 20-bump (1.755mm x

2.015mm x 0.6mm) micro SMD and operates over a 2.7V to

5.5V input voltage range and a −40°C to +85°C temperature

range.

PWM Input for Content Adjustable Brightness Control

(CABC)

●

Five Low-Voltage Current Sinks for Indicator LEDs

●

Integrated Charge Pump for Improved Efficiency and VIN

Operating Range

Internal Pattern Generation Engine

●

Fully Configurable LED Grouping and Control

Four Programmable Over-voltage Protection Thresholds

(16V, 24V, 32V, and 40V)

Programmable 500kHz and 1MHz Switching Frequency

27mm²Total Solution Size

●

Applications

Power Source for Smart Phone Illumination

●

Display, Keypad and Indicator Illumination

RGB Indicator Driver
