FEATURES  
APPLICATIONS  
2
•
Drives up to 3 Parallel High-Voltage LED  
Strings at 40V Each with up to 90% Efficiency  
•
Power Source for White LED Backlit LCD  
Displays  
•
•
0.4% Typical Current Matching Between  
Strings  
•
Programmable Keypad Backlight  
DESCRIPTION  
The LM3532 is  
256 Level Logarithmic and Linear Brightness  
Control with 14-Bit Equivalent Dimming  
I2C-compatible Interface  
a
500 kHz fixed frequency  
asynchronous boost converter which provides the  
power for 3 high-voltage, low-side current sinks. The  
device is programmable over an I2C-compatible  
interface and has independent current control for all  
three channels. The adaptive current regulation  
method allows for different LED currents in each  
current sink thus allowing for a wide variety of  
backlight + keypad applications.  
•
•
Direct Read Back of Ambient Light Sensor via  
8-bit ADC  
•
•
Programmable Dual Ambient Light Sensor  
Inputs with Internal Sensor Gain Selection  
Dual External PWM Inputs for LED Brightness  
Adjustment  
The main features of the LM3532 include dual  
ambient light sensor inputs each with 32 internal  
voltage setting resistors, 8-bit logarithmic and linear  
brightness control, dual external PWM brightness  
control inputs, and up to 1000:1 dimming ratio with  
programmable fade in and fade out settings.

•
Independent Current String Brightness Control  
Programmable LED Current Ramp Rates  
40V Over-Voltage Protection  
1A Typical Current Limit  
The LM3532 is available in a 16-bump, 0.4mm pitch  
thin DSBGA (1.745 mm x 1.845 mm x 0.6 mm). The  
device operates over a 2.7V to 5.5V input voltage  
range and the −40°C to +85°C temperature range.
