Dallas, Texas –September 14, 2010 –-- Diodes Incorporated (Nasdaq:
DIOD), a leading global manufacturer and supplier of high-quality application
specific standard products within the broad discrete, logic and analog
semiconductor markets, today announced an LED driver tailored to fit low
voltage illumination products operating at between 6V and 30V. The AL8805, a
1A rated buck mode constant current switching converter, will support up to ten
3W LEDs connected in series, suiting a range of low cost ‘safe electrical’ designs
including the ubiquitous MR16 lamp.
The driver’s typical constant current output accuracy of 5%, irrespective of
source voltage and LED chain length, is more than sufficient to meet the needs
of low cost lighting products, ensuring uniform LED brightness and good interlamp
matching without the need for ballast resistors.
With nominal output current determined by external resistor setting, LED
dimming is simply achieved by either a DC voltage or PWM signal on the
AL8805’s control input. A DC voltage between 0.5V and 2.5V yields an output
current between 25% and 100% of nominal, while a PWM signal between normal
CMOS or TTL levels offers a highly flexible 1000:1 dynamic dimming range.
On/off control is provided via a <0.4V signal applied to the same control input.
The LED driver’s enhanced switching speed and low on-resistance provide 1MHz
switching frequency capability which reduces the size of the external
components required in thermally demanding environments. The AL8805 is
provided in the SOT23-5 package. For more information, visit the Company’s
