Austriamicro systems has introduced the AS3665, a decorative light-emitting diode LED driver that delivers amazing lighting effects for mobile phones and other consumer applications. The AS3665 emphasizes sharper colors, smoother color effects and high brightness with minimal design difficulty.
The Austrian Microelectronics AS3665 Ultimate Solution enables infinitely free light mode generation and simultaneous use of lighting and sound. This new decorative light LED driver makes mobile phones, MP3 players, notebooks, portable game consoles, speakers, toys and any audio equipment even more eye-catching. The AS3665 has nine LED channels with currents up to 25 mA per channel. Each channel has a dedicated 12-bit Pulse Width Modulation (PWM) that provides a stable, smooth color effect for linear, logarithmic and proportional attenuation. The PWM generator has three sequencers and a 1.5Kb memory to eliminate the need to add external processors or interactive components when storing and processing amazing and complex optical modes.
The company said that the AS3665 can easily program a variety of light modes. To ensure true color during operation, the AS3665 uses a variety of color correction features such as automatic RGB color correction via temperature. The AS3665's audio sync function enables a colorful programmable light mode. With this feature, color LEDs can use the component's audio input such as music or ringtones to smoothly and promptly flash, change the light and dark display or change color. In addition, the AS3665 can synchronize LEDs based on music input. The audio sync function of the light mode is freely adjustable, allowing the user to operate freely, creating a unique color response for any type of music from heavy-duty heavy metal rock to gentle melodies.
To extend battery life, the AS3665 is designed to include a variety of power-saving features. Each channel operates at 10 mA at a differential pressure of less than 50 millivolts and is powered by a high efficiency 150 mA charge pump for automatic switching between 1:1, 1:1.5 and 1:2 modes. To optimize the power consumption of the RGB LEDs, three of the nine channels provide programmable voltage rail switches that can be selected between the battery and the CP voltage to increase efficiency and achieve red and blue/green LED independence. power supply.
Bruce Ulrich, director of marketing for the Austrian microelectronics consumer and communications division, said: “Austriamicrosystems is always a step ahead in serving mobile phone manufacturers and other consumer electronics manufacturers, enabling them to offer exciting new features to the market. Our The AS3665 rhythm light driver enables system designers to offer users more fun and functionality than ever before. This new product really brings light to the sound of mobile devices. The AS3665 extends Austrian microelectronics including flash, backlight, rhythm lights, and A wide range of lighting products including array drivers and powerful lighting management units."
