LED driver delivers high current for LED lamps
Delivering high current for low-voltage LED lamps, the AL8806 buck LED driver can produce a constant current of up to 1.5 A from voltage sources between 6 and 30 V. Suiting MR16 12-V and 24-V LED lamp design, the driver ensures a 5% average LED current accuracy for up to nine high-power LEDs over the wide operating voltage range, helping to significantly improve interlamp luminance matching.
The high-current handling of the driver means it will also meet the needs of the latest multi-die-package LEDs, where current levels above 1 A are required. Maximum output current is simply set via a resistor, and lamp dimming is achieved by applying either a dc voltage or PWM signal that provides a wide range of brightness control which doesn’t overdrive the LED current. Housed in a MSOP-8EP package, the driver features an efficiency as high as 98% and a switching frequency of up to 1 MHz. ($0.55 ea/1,000 — available now.)
