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.
