Diodes' LED Drive Solutions

Advances in high brightness LED technology are enabling the lighting industry to transition to more efficient and reliable solutions, while also introducing new capabilities in control and industrial design. Diodes Incorporated has a long association with the lighting industry and is committed to maintaining its position as a principal supplier of electronic drive and control technology to lighting and luminaire manufacturers. An expanding family of high brightness LED power management and constant current drive products, expanding the range of products from the acquisition of Zetex Semiconductors, with an extensive library of proven reference designs, provides efficient and cost effective solutions for our customers and manufacturing partners.

The examples presented on this page demonstrate the low cost, low component count, flexibility and high performance of typical Diodes' LED drive solutions. These are supported by comprehensive characterization, powerful design tools and an experienced lighting solutions team. The ZXLD1350 constant current driver solution for example, shown here driving XLamp^® LEDs from our solutions partner Cree, provides a minimal component count solution with many control capabilities, including dimming and thermal tracking. Please review the growing list of Diodes' LED drive solutions within the Lighting section and in the overview table below.

Diodes wecomes the opportunity to provide solutions to OEM, ODM and system integration partners. For more information about lighting applications, please contact your local Diodes Incorporated technical support > http://www.diodes.com/contacts/

AL8806 - New 1.5A Cost Effective LED Driver

MT-G shown above. For more information, visit the

Cree microsite:
mtg.cree.com

The AL8806 is Diodes' latest hysteretic buck LED driver designed to drive up to 1.5A LED current. Its low Rds(on) coupled with its low thermal impedance exposed pad MSOP-8EP package enables it to handle the rigors of high current LED driving within space constrained, thermally challenging luminaire designs such as MR16 lamps.

The AL8806 has been developed to drive higher current LEDs, such as Cree's latest multi-die MT-G LED.

AL9910 Evaluation Board

ZXLD1350 Evaluation Board

The ZXLD1360 provides a 1A version of the same circuit topology, whereas the ZXLD1362 and ZXLD1366 are 60V options, ideally suited for linear LED arrays (comprising Cree XPE or XPG, for example) for T8 or T5 fluorescent tube retro-fit or system replacement.
 
The AP8800, AP8801 and AP8802 provide more package variants and additional cost/performance points in the solutions matrix.

ZXLD1321EV1

The ZXLD1321 is optimized for low-voltage, step-down, constant current drive capability that's ideally suited to the Cree MCE LED array for high current, highly integrated solutions.

Our SBR Technology Enhances LED driver applications.
-- Replaces the traditional Schottky.

 
The SBR (Super Barrier Rectifier) technology uses a MOSFET based structure to provide advantages over standard Schottky and PN diodes. The process allows the Vf (forward voltage drop) and Ir (reverse leakage current) to be tuned to provide best in class performance relative to die area, against standard diode technologies. Lower Vf and a much lower temperature coefficient of leakage current allow higher current capabilities per package type and increased thermal stability - both factors of prime interest for LED luminaire converter design.

Thermal Runaway Comparison: SBR2A40PI vs. Standard Schottky

The SBR05M100BLP miniature bridge rectifier is ideal for 12 to 48VAC lighting applications, and provides a space efficient and thermally stable solution.
