Dallas, Texas –January 28, 2011 – 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 the release of the AL9910. Provided in standard
SO-8 and high power dissipation exposed pad SO-8 packages, the AL9910 high
brightness LED driver will support universal AC input voltages from 85V to as
high as 265V. For interior and exterior off-line lighting products, the exposed
pad SO-8 variant in particular helps significantly increase device reliability by
minimizing temperature rise. The AL9910 utilizes a rugged high voltage process
technology allowing it to withstand input voltage surges of up to 500V. System
reliability is further improved by the device’s built-in over-temperature
protection.

Driving LED arrays with a constant current to better control LED brightness,
lighting spectrum and lifetime expectancy, the AL9910 delivers an output of
between a few milliamps and 1A via an external MOSFET operating at a resistor
programmable switching frequency up to 300kHz. Removing the need for a
start-up resistor, a built-in voltage regulator delivers a gate drive to match and
protect the switching MOSFET: 7.5V for the AL9910 and 10V for the companion
AL9910A.

To extend device flexibility, the high efficiency AL9910 offers two separate
dimming inputs for LED brightness control: a linear dimming input controlled by
the application of a dc control voltage, and a low frequency PWM dimming input
that accepts an external TTL compatible control signal with a duty ratio of
0-100% and at a frequency of up to a few kHz. For more information, visit the
