THine starts mass production of its new LED driver products for high-power LED equipments


2014/01/28

TOKYO (January 28, 2014) -- THine Electronics, Inc. (JASDAQ: 6769), the global leader in high-speed serial interface and provider of mixed-signal LSI, today announced its starting volume production of new LED driver products, THL65 series that include THL6516, THL6517, THL6518, THL6521, and THL6523. This new LED driver series 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.
 
This new LED driver products, THL65 series, 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 4 kinds of the constant current LED drivers with the lineup of THL6521/6523 for 1-channel, 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 TSOT23-6 for 1-channel products and QFN 16 pin (3 mm x 3 mm) for multi-channel products that achieve smaller footprints than usual LED drivers for LED back light and lighting systems. In addition, these new products have soft start functions and other protection functions to prevent system damages from abnormal LED failures.
