National Semiconductor Introduces World's Smallest, Fully Integrated Flash LED Driver
National Semiconductor Corporation (NYSE:NSM), the worldwide leader in power management technology, today introduced the world’s smallest fully integrated flash light-emitting diode (LED) driver. The LM2754, featuring low input noise, adjustable output power control and automatic LED shutdown, delivers up to an 800 mA load in handheld applications.
High Power LED Driver is Optimized for Driving Single- and Multiple-Die Flash LED Technologies in Handheld Applications
Many of today’s cellular phones feature built-in digital cameras capable of both high-resolution still and video images. Gains in camera technologies have created the need for a high-power white-light source for camera use indoors or in dim ambient light.
White LEDs, already popular for backlighting color displays, have emerged as the flash light source in camera phones. National’s LM2754 charge-pump-based, high current, flash LED driver boasts a unique circuit design that enables several exclusive system-level features, such as reduced noise spikes on the input and adjustable output power control to prevent battery drain.
