In a 6 W MR16 application, the device operates flicker-free with most common LED lighting transformers at a power factor of 0.9 and THD of 30%.

Combining two DC-DC regulators in the 5 mm x 6 mm SO-8EP package, the AL8820 operates in continuous-current mode and employs an innovative control scheme to ensure high compatibility with most commonly used electronic transformers.  An ultra low RDSON internal 40 V/2 A NDMOS switch helps minimize power losses while supporting the delivery of large output powers in a wide range of 5 W to 7 W MR16 LED lamps.

The device features a wide 5 V to 36 V input voltage range and an output current up to 2 A can be achieved.  A switching frequency of up to 1 MHz means that smaller-sized external inductors and capacitors can also be used with the device for MR16 solutions, helping to further minimize overall circuit footprint and BOM cost.

The AL8820’s comprehensive integrated protection features include: under-voltage lock out, output short circuit, output open-circuit, over-current, over-voltage and over-temperature protection.

The AL8820 LED driver converter for MR16 lamp design is priced at $0.45 each in 10K quantities.
