Diodes Inc. LED Drivers Bring Smaller Footprint and Energy Savings to Lighting Applications

Oct. 6, 2008
Date Announced: 06 Oct 2008 Dallas, TX … Diodes Incorporated (NASDAQ:DIOD) further extends its Zetex LED Driver Series with the introduction of three new miniature LED drivers that improve accuracy and thermal performance. Provided in TSOT23-5 and thermally enhanced DFN6, the highly integrated ZXLD-1352, -1356 and –1366 deliver adjustable output currents of 350mA, 550mA and 1A, respectively, need the support of just three discrete external components, and suit a broad range of automotive, architectural and industrial lighting applications.The ZXLD drivers are continuous mode, inductive step-down converters, specifically designed for driving single or multiple high brightness LEDs, and characterized by their ease of configuration and operation. Nominal output current, set by a resistor, is easily adjusted by applying a PWM or DC voltage control signal, and allows precise matching of brightness requirements. A low-level control signal turns the output off and puts the driver into standby.The ZXLD1356 and ZXLD1366 provide an output current accuracy of typically better than 1%, providing users with highly precise current matching at working voltages up to 60V. Capable of producing output powers of 30W and 48W respectively, these TSOT23-5/DFN63, 3mm x 3mm packaged drivers support up to 15 LEDs, and an array of applications requiring minimum footprint and maximum efficiency.The ZXLD1352 operates from a 7V to 30V supply, and is capable of producing an output current of up to 350mA. This TSOT23-5, 2.8mm x 2.9mm packaged driver provides up to 8W of power for driving chains of up to 10 LEDs. With a large PWM dimming ratio of 1000:1, the driver offers highly flexible brightness control and accurate color mixing.Available now from authorised distributors, at 1,000 quantity the ZXLD1352 (TSOT23-5) is priced at 0.98USD, the ZXLD1356 at 1.32USD and 1.40USD respectively for TSOT23-5 and DFN6 variants, and the ZXLD1366 at 1.82USD and 1.92USD respectively for the same package options. Delivery is 4-6 weeks in production volumes.About Diodes Incorporated:Diodes Incorporated (Nasdaq: DIOD), an S&P SmallCap 600 and Russell 3000 Index company, is a leading, global manufacturer and supplier of high-quality, application-specific, standard products within the broad, discrete and analog semiconductor markets.
