Texas Instruments LM2751 Regulated 2X, 1.5X Switched Capacitor White LED Driver LM2751SDX-A/NOPB

The LM2751 is a regulated switched capacitor white LED driver that operates with 2X and 1.5X voltage conversion. It supports output voltage options of 4.5V and 5.0V, with a regulation accuracy of within 3%. The device can deliver up to 150mA output current at 4.5V and 80mA at 5.0V, making it suitable for various LED applications, including display and keypad backlighting. The input voltage range is from 2.8V to 5.5V, and it features a low shutdown current of less than 1µA. The LM2751 operates efficiently with peak efficiencies exceeding 90% and does not require an inductor, simplifying the design. It offers programmable switching frequencies of 725kHz, 300kHz, 37kHz, or 9.5kHz, allowing flexibility in application requirements. The device is housed in a compact 10-pin SON package, measuring 3mm x 3mm x 0.8mm, which aids in space-constrained designs.
