The LM2759SD/NOPB is an integrated circuit (IC) component manufactured by Texas Instruments. It is primarily designed for driving high-current white light-emitting diodes (LEDs) in portable devices. This IC is specifically tailored to cater to the increasing demands of LED backlighting in handheld devices like smartphones, tablets, and other portable electronics.
Key features of the LM2759SD/NOPB include:
1. Dual-Channel LED Driver: The LM2759SD/NOPB incorporates two integrated channels for driving high-current LEDs, making it suitable for applications requiring multiple light sources, such as displays and indicators.
2. High Efficiency: With a built-in low-dropout (LDO) linear regulator, this IC provides efficient power management by ensuring a regulated voltage supply to the LEDs, resulting in improved power utilization and longer battery life.
3. Adjustable LED Current: The LM2759SD/NOPB allows precise control of the LED brightness by implementing an adjustable current control for both channels individually. This flexibility enables precise luminance adjustments for different lighting conditions and user preferences.
4. Wide Operating Voltage Range: This IC can operate efficiently within a wide supply voltage range, typically between 2.7V and 5.5V, making it compatible with various power sources commonly found in portable devices
