Lattice Technology Introduces Full Circuit Interface Six-Chip LED Driver Series
Introduction: Lattice Technology Co., Ltd. announced that it has been able to supply LDS8867, LDS8868 and LDS8869 product samples. By using its patented PowerLite? current regulator, the new series of LED driver in Lattice can be based on the charge pump. Achieve 95% performance and extend battery life. Lattice develops analog and mixed-signal semiconductor devices for consumer electronics products, including color display drivers, energy management, LED drivers and audio integrated circuits.
The latest LED drivers support up to six LEDs for portable backlighting applications and up to 32 mA per circuit. The new single-circuit interface product will be added to the previously announced non-voltage memory memory interface product, providing handset designers with more flexible new performance/interface options.
Adolfo Garcia, Senior Director of Lattice LED Drivers, said: Lattice has always been committed to improving the efficiency of mobile phones to match the development of multimedia functions outside of voice communications, such as browsing the Internet, taking photos, and even video clips, launching integrated GPS from mobile phones. And mobile games, etc. As portable devices continue to evolve, improving LED driver performance is a trend. Lattice's LED drivers will continue to focus on improving the core features required for portable devices: longer battery life.
Lattice's ultra-low voltage regulated PowerLiteTM current regulator consumes a conversion voltage of only 50 millivolts, which lasts longer than other products. In addition, this patent-pending technology addresses the biggest problem with charge pump LED drivers, the high-performance state (1-fold mode) to lower-performance transitions. By reducing the voltage drop across the drive to 50 millivolts, battery life can be extended by 20%.
Introduction to LDS8869
The LDS8869 is a high-performance multi-mode boost mode fractional charge pump with an ultra-low voltage drop that can drive up to six LEDs. It includes a 1.33x boost mode fractional charge pump and an ultra low dropout PowerLiteTM current regulator for up to 95% performance. The 1.33x mode does not require an additional external capacitor. Its EN/SET logic input gives the chip and LED current control.
The highest LED current is 32 mA and can be adjusted from 0.5 mA to 32 mA. The boost mode charge pump supports input voltages from 2.7 volts to 5.5 volts. The device is available in a 16-pin TQFN package (3 mm x 3 mm) with a height of only 0.8 mm.
