Arctic Sand Technologies introduces game-changing highest efficiency, lowest profile LED driver ICs

BURLINGTON, Mass.--(BUSINESS WIRE)--Arctic Sand Technologies (www.arcticsand.com), the performance and space saving leader in power conversion ICs, today launched its ARC1C0608 IC – a ‘triple-play’ delivering industry leading power conversion efficiency, in the lowest ‘z’ height profile and smallest footprint in the industry. The ARC1C0608 is an LED driver that is so efficient that it is able to save 0.5W (in a typical 2 W host platform) when deployed in backlights for tablets and other smart mobile devices, thus enabling a new generation of low power, long battery life, ultra-thin devices.

Arctic Sand is a spin-out of MIT with technology based on exclusively-licensed MIT patents co-authored by Arctic Sand’s founder and Chief Scientist David Giuliano, as well as many new Arctic Sand-issued patents. Arctic Sand IC’s feature TIPS (Transformative Integrated Power Solution) a patented ‘staged pipeline’ architecture that effectively reduces dependence on inductance, inherently lowers EMI and ripple and uniquely enables ultra-low profile solutions with industry-leading power conversion efficiency performance – addressing key pain points for mobile computing and data centers.

The ARC1C0608 LED driver has six integrated programmable current sinks, integrates all MOSFETs, its control and driver circuitry, and features state of the art dimming options within a tiny WLCSP-35 package. The TIPS™ boost architecture delivers LED efficiency levels of 93.5% peak for up to six LED strings at 3.8V input voltage.

Comments Stephen Allen, Vice President Sales & Marketing: “Our patented architecture ensures that the ARC1C0608 is the most efficient LED driver in the market, and our efficiency advantage increases as platform packaging profiles reduce. This is game changing! For example, with a 1mm inductor we are 10% more efficient than leading competitors, halving the losses in the boost converter, and extending battery run-time in tablets by about one hour. OEMs of ultra-portable devices all tell us that the LCD backlight is a major pain-point today, and saving 0.5W in a UHD display is highly compelling.”

Arctic Sand’s ARC1C0608 LED driver runs off a single cell Li-Ion battery input voltage of 2.7V - 5.5V and delivers up to 30V output for maximum flexibility in the assignment of LEDs to strings and selection of LED forward voltage. The IC includes extensive fault protection including over-current, output over-voltage and under-voltage protection, LED open and short protection (eliminating the need for an external disconnect switch). An I²C 6.0-compatible serial interface operating at up to 1MHz is included.

The IC facilitates linear, PWM, or hybrid PWM dimming with either linear or logarithmic function, and phase-shifted PWM dimming can be employed among active strings to eliminate audible noise.

The ARC1C0608 LED driver is sampling now.

Arctic Sand公司推出高效,小型LED驱动器IC

马萨诸塞州伯灵顿 - (美国商业资讯) - 北极沙科技(www.arcticsand.com),在功率转换IC的性能和节省空间的领导者,今天推出了其ARC1C0608 IC - 一个'三网合一'提供业界领先的功耗转换效率,最低的'Z'高度轮廓和最小的体积在同行业中。该ARC1C0608是一个LED驱动器,非常有效,部署在背光时平板电脑和其他智能移动设备,从而使新一代低功耗的是能够节省0.5W(在一个典型的2 W主机平台),长电池寿命,超薄器件

北极砂是一种分拆出来麻省理工学院基于独家授权专利MIT北极沙子的创始人和首席科学家戴维·朱利亚诺,以及许多新的北极砂授权专利合作撰写的技术。北极沙IC的功能TIPS(转型集成电源解决方案)获得专利的“上演管线”架构,有效地降低了电感的依赖,本质上降低EMI和纹波并唯一能够与业界领先的电源转换效率表现的超低调的解决方案 - 解决关键的痛点移动计算和数据中心。

该ARC1C0608 LED驱动器有六个集成可编程电流吸收器,集成了所有的MOSFET,它的控制和驱动电路,并设有一个微小的WLCSP-35封装内的艺术调光选项状态。提示™升压架构提供LED 93.5%的峰值效率水平在3.8V输入电压高达6个LED串。

评论斯蒂芬·艾伦,销售和市场营销副总裁:“我们的专利架构确保ARC1C0608是市场上最高效的LED驱动器,我们的效率优势会随着平台的包装型材减少。这是改变游戏规则!例如,对于1mm的电感器已是10%,比主要竞争对手更有效率,减半在升压转换器中的损失,以及由约一小时延长电池运行时间的片剂。超便携设备的OEM厂商都告诉我们,LCD背光是一个重大的痛苦点的今天,在UHD显示器节省0.5W非常引人注目。“

北极沙的ARC1C0608 LED驱动器运行了2.7V的单节锂离子电池输入电压 - 5.5V,并可提供高达30V的输出为LED的分配字符串和LED正向电压的选择了最大的灵活性。该IC包括广泛的故障保护,包括过流,输出过压和欠压保护,LED开路和短路保护(省去了外部断路开关的需要)。高达1MHz的操作一个I²C6.0兼容的串行接口也包括在内。

该IC有助于线性,PWM,或混合使用PWM线性或对数函数,和相移PWM调光调光可以主动串中被用来消除噪音。

该ARC1C0608 LED驱动器现已提供样品。
