LED Driver from Diodes Offers High E-Transformer Compatibility in Non-Dimmable MR16 Lamp Design

Business Wire
Diodes Incorporated (Nasdaq: DIOD), a leading global
manufacturer and supplier of high-quality application specific
standard products within the broad discrete, logic and analog
semiconductor markets, today introduced the AL8820 LED driver
converter. This device is a compact, two-stage, boost/buck
non-dimmable MR16 lamp design solution that is simultaneously
characterized by high power factor, low total harmonic distortion
(THD) and low-output current ripple. For example, in a 6W 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 5mm x 6mm 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
40V/2A NDMOS switch helps minimize power losses while supporting
the delivery of large output powers in a wide range of 5W to 7W
MR16 LED lamps.
The device features a wide 5V to 36V input voltage range and an
output current up to 2A can be achieved. A switching frequency of
up to 1MHz 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. Further information is available at www.diodes.com.
