The high current handling of the AL8806 means it will also meet the needs of the latest multi die package LEDs, where current levels above 1 A are required. The simple, cost-effective driver is packaged in the small footprint low thermal impedance MSOP-8EP, supporting higher LED current drive at higher ambient operating temperatures. Device efficiency is high at up to 98%.
Maximum output current is simply set via a resistor and switching at a frequency of up to 1 MHz, the driver helps reduce the size of supporting external components, enabling PCB size to be minimized. Lamp dimming is achieved by applying either a DC voltage or PWM signal that provides a wide range of brightness control that doesn’t over drive the LED current.
The AL8806 30 V, 1.5 A buck LED driver is priced at $0.55 each in 1k quantities.
