Provided in standard SO-8 and high-power-dissipation exposed-pad SO-8 packages, the AL9910 high-brightness LED driver supports universal ac input voltages from 85 to as high as 265 V. For interior and exterior off-line lighting products, the exposed-pad SO-8 version helps raise reliability by minimizing temperature rise and, through its rugged high-voltage process technology, by withstanding input voltage surges of up to 500 V.
The device delivers an output of between a few milliamperes and 1 A via an external MOSFET operating at a resistor programmable switching frequency up to 300 kHz. Additional features include 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 accepting an external TTL-compatible control signal with a duty ratio of 0% to 100% and at a frequency of up to a few kHz. It also has an internal regulator and overtemperature protection. ($0.60 ea/1,000 — available now.)
