The Texas Instruments TPS61187 is a highly integrated white-light-emitting-diode (WLED) driver tailored for notebook LCD backlight applications. Operating over an input voltage range of 4.5 V to 24 V, this component integrates a 2-A, 40-V MOSFET in its design, offering a maximum output voltage of 38 V. It provides up to six current sinks capable of supplying a maximum of 30 mA each, accommodating up to 60 WLEDs in total. The TPS61187 supports both automatic phase-shift dimming and direct PWM dimming methods, allowing for versatile control over the backlight brightness with dimming ratios reaching 100:1 at 20 kHz and 10000:1 at 200 Hz in direct PWM mode. Programmability extends to its switching frequency, which can be set from 300 kHz to 1 MHz, facilitating optimization for efficiency and performance. This component also incorporates protection features against overvoltage, open/short WLED conditions, and thermal shutdown, ensuring reliable and safe operation in demanding notebook backlighting scenarios.
