What is LM2759SD/NOPB used for?
The LM2759SD/NOPB is designed for camera flash LED drivers in smartphones, tablets, and portable digital cameras where a single high-current LED must deliver 1.5 A flash pulses from a 3.6 V Li-ion cell while supporting dimmed torch mode at lower continuous currents. It is also used in industrial machine-vision strobe lighting and barcode scanner illumination systems requiring precise current-controlled LED pulses synchronized to an image sensor trigger.

Frequently Asked Questions
What maximum flash current does LM2759SD/NOPB support and for how long can it sustain that current?
The LM2759SD/NOPB drives a single high-brightness LED at up to 1.5 A flash current for pulse durations typically up to 300 ms, as limited by junction temperature. For torch mode (continuous operation), the device limits current to approximately 200 mA to prevent thermal damage, balancing brightness and safe continuous operation from a Li-ion battery.
How does the serial interface on LM2759SD/NOPB control LED brightness and operating mode?
The LM2759SD/NOPB uses a serial data interface to program flash current level, flash timeout duration, and torch mode current via a single data line, allowing a microcontroller to set 16 or more discrete current steps from under 50 mA torch to 1.5 A flash. This serial control replaces multiple analog resistors and GPIO pins, simplifying PCB routing in compact smartphone camera modules.
What input voltage range does LM2759SD/NOPB support and is it compatible with Li-ion batteries?
The LM2759SD/NOPB operates from an input voltage of 2.7 V to 5.5 V, covering the full discharge range of a single-cell Li-ion battery (2.7 V discharged to 4.2 V fully charged) as well as 5 V USB power. The integrated charge pump ensures the LED current remains regulated at 1.5 A even when the battery voltage drops below the LED forward voltage of approximately 3.2 V.
In which compact package does LM2759SD/NOPB come and what thermal considerations apply at 1.5 A flash?
The LM2759SD/NOPB is housed in a 12-pin WSON (2 mm x 2 mm) package with an exposed thermal pad that must be soldered to a PCB copper area of at least 10 mm² to keep junction temperature below 125 °C during repeated 1.5 A flash pulses. Adequate thermal spreading is critical for applications requiring flash repetition rates above 1 Hz in ambient temperatures above 40 °C.
