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, maintaining regulation within 3% across an input voltage range of 2.8V to 5.5V. The device can deliver up to 150mA output current at 4.5V and 80mA at 5.0V, making it suitable for applications such as white LED display and keypad backlighting. This driver features a peak efficiency exceeding 90% and operates without the need for an inductor, utilizing only four low-cost ceramic capacitors. The switching frequency is programmable, allowing options of 725kHz, 300kHz, 37kHz, or 9.5kHz, which can help minimize conducted noise. The LM2751 is housed in a compact 10-pin SON package measuring 3mm x 3mm x 0.8mm, making it a space-efficient solution for various electronic designs.
