Buck led driver delivers higher current for low voltage led lamps

The AL8806 buck led driver from Diodes is designed to produce a constant current of up to 1.5A from voltage sources of between 6 and 30V.

Suitable for MR16, 12 and 24V led lamp designs, the driver ensures a 5% average led current accuracy for up to nine high power leds over the operating voltage range to improve inter lamp luminance matching. Its high current handling also means it can meet the needs of the latest multi die package leds, where current levels above 1A are required.

The driver is packaged in a small footprint, low thermal impedance MSOP-8EP and supports higher led current drive at higher ambient operating temperatures. Device efficiency is rated at up to 98%.
