TPS61199PWPR - TI Function Overview

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.
FEATURES
• 8V to 30V Input Voltage
• Integrated High-Power Boost Controller
• Adaptive Boost Output for LED Voltages
• Drive up to Eight LED Strings in Parallel
• Maximum 65mA for Each LED String
• 3% Current Matching Between Strings
• 5000:1 PWM Dimming Ratio at 200Hz
• MOSFET Over-current Protection
• Programmable LED Short Protection
• Adjustable LED Open Protection
• Thermal Shutdown Protection
• 20-pin SOP Package and TSSOP Package with PowerPAD™
APPLICATIONS
• Monitor LCD Backlight
• LCD TV Backlight
• General LED Lighting
