THine releases its new LED driver products for high-power LED equipments


TOKYO (May 28, 2013) -- THine Electronics, Inc. (JASDAQ: 6769), the global leader in high-speed serial interface and provider of mixed-signal LSI, today announced its new LED driver products, THL6516, THL6517, and THL6518. These new LED drivers are suitable for applications with high-power LED equipments such as back lights of LCD panels and LED lightings as well as mobile phones, automotive navigation systems, tablet PCs, LCD monitors, amusement equipments, digital camcorders, digital still cameras, automated teller machines (ATM), and other industrial equipments.

These new LED drivers have a build-in boost converter circuits that can convert the usual 5V power supply to the right voltage for LED power supply. This integration enables LED back light systems to consist of one chip simply. THine supplies 3 kinds of the constant current LED drivers with the lineup of THL 6516 for 4-channel, THL6517 for 6-channel, and THL6518 for 8-channel, so that customers can select the suitable products and optimize the systems by product models.

The new LED drivers are packaged in QFN 16 pin (3 mm x 3 mm) and achieve smaller footprints by 40% approximately than usual LED drivers for LED back light and lighting systems. In addition, THL6516 / 6517 / 6518 have soft start functions and other protection functions to prevent system damages from abnormal LED failures.

THine plans to start volume production in the forth quarter 2013 and enhance its LED driver lineups.
