LED driver for MR16 lamps

25 February 2015 Opto-Electronics Power Electronics / Power Management

The AL8820 LED driver converter from Diodes Incorporated is a two-stage, boost/buck non-dimmable MR16 lamp design solution characterised by high power factor, low total harmonic distortion (THD) and low output current ripple. Combining two DC-DC regulators in the 5 x 6 mm SO-8EP package, the IC operates in continuous-current mode and employs an innovative control scheme to ensure high compatibility with most commonly used electronic transformers. It features a 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 external inductors and capacitors can be used.
