February 18, 2013, Seoul - Infineon Technologies' (Korea CEO Lee Seung-soo) new 60V DC/DC LED driver delivers outstanding power conversion efficiency, standard current accuracy ensuring consistent light output, and industry-first adjustable thermal protection that safeguards lighting elements from damage due to overheating. Featuring a wide input voltage range from 4.5V to 60V, output current adjustable up to a maximum of 0.7A or 1.5A, and digital or analog dimming inputs supporting dimming shrinkage ratios up to 3000:1, the new ILD6070/ILD6150 drivers provide manufacturers with the flexibility to produce diverse products using the same driver.

By adding 60V products to its portfolio, Infineon enables manufacturers to support up to 18 LEDs on a single lighting string (the 40V products commonly available support a maximum of 12 LEDs). This allows manufacturers to either reduce costs or achieve higher lumens in lighting systems.

Dr. Christian Burrer, division head of AC/DC and lighting IC products at Infineon Technologies, stated: "As the lighting industry's transition to LED-based lighting fixtures accelerates (expected to show 30% growth rate in coming years), manufacturers must do their best to secure competitiveness in terms of performance and cost while innovating engineering design. Infineon's goal is to provide a single supply solution for high-efficiency power conversion and control elements optimized for lighting system design."

The new LED driver expands Infineon's portfolio of switch mode, buck (step-down) topology for low-voltage driven lighting applications including indoor and outdoor systems used in residential, commercial, and industrial environments. Since these products operate at switching frequencies up to 1MHz, they reduce the size of external components required in the design, thereby reducing manufacturing costs and PCB space. The high efficiency and resulting improved temperature performance of the driver also enable size reduction.

The performance characteristics of the new device are as follows:
• Maximum 98% DC/DC conversion efficiency improves overall luminaire efficiency and reduces thermal load.
• 3% current accuracy across the entire input range from 4.5V to 60V provides excellent reliability for light output.
• Adjustable thermal protection reduces light output when reaching threshold temperature without switching the lighting off. Through this function, LED lighting always operates within non-critical temperature ranges, thereby significantly extending operating life.

Availability
Samples of the ILD6070/ILD6150 drivers are scheduled to be available in March.

Designers working with Infineon LED driver ICs can access the "Infineon Light Desk" design tool (www.infineon.com/lightdesk) to rapidly design and simulate LED driver circuits for all types of LED applications through optional redesign and download of design summaries including specifications, schematics, and BOM.
