The TPS61161DRVRG4 from Texas Instruments is a boost converter designed to drive LEDs in series, specifically for backlight applications. It features digital and PWM brightness control, allowing for flexible illumination adjustments.
This device operates with an input voltage range of 2.7V to 18V and can provide an output voltage up to 38V. It has a fixed switching frequency of 600kHz, which helps reduce output ripple and allows for the use of small external components. The integrated switch FET is rated for 40V. The driver offers a peak efficiency of up to 90% and includes features like EasyScale 1-Wire Interface and load disconnect during shutdown.
The TPS61161DRVRG4 is available in a compact 6-WSON (2x2 mm) package, suitable for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C. The part also includes built-in soft start functionality and 38-V open LED protection.
