synchronous boost which provides the power for a  
single flash LED at up to 1.5A or dual LEDs at up to  
750 mA each. The high-voltage backlight driver is a  
dual-output asynchronous boost which powers dual  
LED strings at up to 40V and 30 mA per string. An  
adaptive regulation method in both boost converters  
regulates the headroom voltage across the respective  
source/sink to ensure the LED current remains in

LM3639A's flash driver is a 2MHz or 4MHz fixed-  
frequency synchronous boost converter plus 1.5A  
constant current driver for a high-current white LED.  
The high-side current source allows for grounded  
cathode LED operation providing Flash current up to  
1.5A. An adaptive regulation method ensures the  
current source remains in regulation and maximizes  
efficiency.  
The device is controlled by an I2C-compatible  
interface. Features for the flash LED driver include a  
hardware flash enable (STROBE) allowing a logic  
input to trigger the flash pulse, and a TX input for  
synchronization to RF power amplifier events or other  
high current conditions. Features for the LCD  
backlight driver include a PWM input for content  
adjustable backlight control, 128 exponential or linear
