  SAN JOSE, CA, Jun 13 (MARKET WIRE) -- 
Micrel, Inc. (NASDAQ: MCRL), an industry leader in analog, high bandwidth
communications and Ethernet IC solutions, today unveiled a pair of new
linear WLED Drivers to further expand its lighting portfolio of products.
The MIC4801/MIC4802 are single channel, constant-current sink LED drivers
designed for architectural, landscape, and general LED lighting products.
The MIC4801/MIC4802 are currently available in volume quantities with
pricing starting at $0.58 and $0.62 respectively for 1Ku quantities.
Samples can be ordered on line at: www.micrel.com/ProductList.do. 

    "The MIC4801/MIC4802 LED drivers are simple to use and do not require an
inductor, eliminating noise, minimizing component count and simplifying
numerous designs," noted Doyle Slack, senior marketing director for
Analog. "With its Ultra Fast PWM(TM) Control interface, both the MIC4801
and the MIC4802 can achieve brightness control down to 1 percent duty
cycle." 

    The MIC4801 and the MIC4802 are high efficiency White LED (WLED) drivers
designed to drive a single LED up to 600mA and 800mA respectively. The
MIC4801 and the MIC4802 provide high efficiency as this architecture has
no switching losses present in traditional charge pumps or inductive
boost circuits. Both devices feature low dropout voltages which allow the
LEDs to be driven directly from low voltage sources and thus eliminates
switching noise/losses which accompany the use of boost circuitry.

    The high accuracy (+/-1 percent typical) current regulated WLED ensures
uniform display illumination under all conditions. The brightness is
controlled through an Ultra Fast PWM(TM) Control interface operating down
to less than 1 percent duty cycle.

    The MIC4801 and the MIC4802 are available in an 8-pin SOIC package and
8-Pin ePad SOIC package respectively with a junction temperature range of
-40degC to +125degC. All supporting documentation, including the
datasheets, can be found on Micrel's website at: http://www.micrel.com.
