Unique power conversion architecture achieves ‘massive’ power savings enabling next generation ultra-thin tablet/mobile platforms.
Burlington, MA., – 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.
