FEATURES
DESCRIPTION
The LM3697 is a high-efficiency three string power
Drives Three Parallel High-Voltage LED Strings
source for backlight or keypad LEDs in smart-phone
for Display and Keypad Lighting
handsets. The high-voltage inductive boost converter
High-Voltage Strings Capable of up to 40V
provides the power for three series LED strings for
Output Voltage and up to 90% Efficiency
display backlight and keypad functions (HVLED1,
HVLED2 and HVLED3).
Up to 30 mA per Current Sink
11-Bit Configurable Dimming Resolution
An additional feature is a Pulse Width Modulation
(PWM) control input for content adjustable backlight
PWM Input for Content Adjustable Brightness
control, which can be used to control any high-
Control (CABC)
voltage current sink.
Fully Configurable LED Grouping and Control
The
LM3697
is
fully
configurable
via
an
I2C-
Four Configurable Over-Voltage Protection
compatible interface. The device is available in a 12-
