LED driver delivers higher current for low voltage LED lamps
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.
Pricing
The AL8806 30 V, 1.5 A buck LED driver is priced at $0.55 each in 1k quantities.
