The TPS61181ARTER from Texas Instruments is a highly integrated LED driver solution for media-size LCD backlighting in notebook applications. This device features six current sink regulators, providing high-precision current regulation and matching for up to 10 WLEDs in series per channel.
Key electrical specifications include an input voltage range of 4.5V to 24V and a maximum output voltage of 38V. It operates with a switching frequency of up to 1MHz and offers a duty cycle of up to 94%. Each channel can deliver up to 30mA of LED current, with typical current matching and accuracy of 1%. The device supports PWM brightness dimming up to 1000:1.
Designed for ease of use, the TPS61181ARTER includes integrated loop compensation and requires small external components. It operates within an ambient temperature range of -40°C to 85°C. The package is a 16-WQFN (3x3) with surface mount type.
Features such as load disconnect during shutdown, WLED open and short protection, and built-in soft start contribute to a robust design. The device is suitable for applications requiring efficient and precise LED backlight control.
