One of Industry's Smallest Camera Flash LED Driver Solutions Delivers Up to 1.2A, Ultra-Compact 1.3mm x 1.3mm Package
SAN JOSE, Calif. -- Micrel, Inc. (Nasdaq:MCRL), an industry leader in high performance linear and power solutions, LAN and timing and communications solutions, today introduced the MIC2873/MIC2874, an ultra-compact, camera flash LED driver that integrates a 1.2A boost converter and LED driver circuit into a small 9 pin, 1.3mm by 1.3mm chip scale package. Operating from 2.7V to 5.5V and featuring up to 92 percent efficiency, these solutions are ideally suited for Li-Ion battery operated portable applications such as phone cameras, tablet computers, handset video equipment, and digital cameras. High switching frequencies (2MHz for the MIC2873 and 4MHz for the MIC2874) allow for the use of a miniature size chip inductor and small input/output capacitors, thereby reducing the total power footprint to a solution size to less than 10mm squared. In addition, these devices can operate in either a flash or torch mode with the ability to provide a boost or linear output using a single wire communication interface or through external pins. The MIC2873/MIC2874 are available in volume with 1,000 quantities pricing starting at $0.26/$0.30 respectively. Samples can be ordered on line at: http://www.samplecomponents.com/scripts/samplecenter.dll?micrel.
Micrel's new generation of high brightness Flash LED drivers address the growing market of tablets and mobile phones by reducing solution size for LED flash applications with a 40 percent reduction in package size.
"We are excited to offer a leading edge 4 MHz switching frequency camera flash solution to our customers. These highly differentiated products are ideal for smart phones or tablet applications where the board space is premium," stated Brian Hedayati, vice president of marketing for high performance linear and power solutions at Micrel. "The MIC2873/MIC2874 high efficiency and low standby current also help to increase battery life especially when operating as video flash or when in torch mode."
These parts are fully protected against overvoltage and overcurrent conditions with a configurable time-out feature. In addition, these ICs provide LED short circuit detection and a true load disconnect feature for best system reliability. The MIC2873/MIC2874 devices are fully specified with an ambient temperature range from -40 deg C to 85 deg C.
