The Texas Instruments TPS61195RUYT is a step-up (boost) DC DC regulator designed specifically for backlight applications. It integrates eight current-sink outputs, each rated for 30 mA, and supports PWM dimming for brightness control across the LED string.
The output voltage range spans 4.5 V to 45 V, which covers series-connected LED strings in medium-to-large LCD panels.
Yes, PWM dimming is supported. This allows the backlight brightness to be controlled by an external PWM signal from the display timing controller or an MCU.
