The global semiconductor supplier STMicroelectronics across multiple electronic applications (ST) to expand the energy efficiency of mobile device solutions lineup, the launch of the new white light emitting diode (LED) driver chip --STLA02. The new product can simplify the design of high performance liquid crystal display and keyboard backlight. Compared with traditional fluorescent lamp backlight solution, white LED backlight can reduce power consumption, thus extending the intelligent mobile phone, game machine, navigation equipment and other portable devices and battery life. STMicroelectronics new product STLA02 (High-side) has high side current detection function, can further improve the backlight circuit design, backlight negative (low voltage side) terminal can be connected directly to the ground, without connecting a low voltage side current detection circuit, which simplifies the design of circuit board printing, reduce the number of connecting lines of the backlight, and to improve the reliability of the whole system. STLA02 can drive up to six LED, the minimum power supply voltage of 2.5 volts, the system can be used by a lithium battery power supply; the maximum working voltage of 18 volts, so that the new product can be matched with various battery power. STLA02 further expand STMicroelectronics to reflect the portable equipment product lineup. The new products will help reduce the size of the versatile portable products and extend the life of the battery through the unique advanced process and the leading global integration and energy efficiency. Other products include portable devices for high efficiency DC-DC converter (DC-DC), class D audio amplifier, audio chip, ambient light sensor (Ambient Light Sensor), a motion sensor, and high performance and low power microcontroller (STM8 and STM32).
