DESCRIPTION  
The TPS61199 provides highly integrated solutions for large size LCD backlighting. This device integrates a  
current-mode boost controller and eight current sinks for driving up to eight LED strings with multiple LEDs in  
series. Each string has an independent current regulator with current matching between strings reaching 3%  
regulation accuracy. The IC adjusts the boost controller's output voltage automatically to provide only the voltage  
required by the LED string with the largest forward voltage drop plus the minimum required voltage at that  
string's IFBx pin, thereby optimizing the driver's efficiency.  
The TPS61199 provides PWM brightness dimming with an external PWM signal. The PWM signal’s maximum  
frequency can be as high as 22kHz. Dimming ratios up to 5000:1 can be achieved with 200Hz PWM signal. The  
TPS61199 integrates over current protection for the switch FET, soft startup, LED short protection, LED open  
protection, and over temperature shutdown protection. The TPS61199 device is available in 20-pin SOP and  
HTSSOP package.
