Original Press Release:
Picor Introduces PI3101 Cool-Power(TM) 60 Watt Isolated DC-DC Converter Setting a New Benchmark for Size and Power Density
No. Smithfield, RI, USA...Picor, a subsidiary of Vicor Corporation (NASDAQ:VICR) specializing in the design and development of high performance power management solutions, today announced the introduction of the PI3101 Cool-Power™ high-density isolated DC-DC converter delivering 60W of output power in half the size of existing solutions, setting a new standard for power density by delivering over 105W per square inch. The PI3101 combines isolation, voltage transformation and output regulation into a high density, surface-mount Power-System-in-Package (PSiP) platform with a tiny footprint (0.57 inches squared) and very low profile (0.27 inches), making it ideal for applications where board space, airflow and height dimensions are critical.
The PI3101 operates over a wide input voltage range of 36V to 75Vdc while providing a regulated 3.3V output at up to 18 Amps output current. The PI3101 can withstand input voltage transients of up to 100V for 100ms and provides 2250V input-to-output isolation.
The PI3101 is an ideal solution addressing the ever-challenging requirements of end-systems such as advanced telecom and wireless infrastructure, networking and communications, Power-over-Ethernet applications and high speed server platforms where power conversion density is critical in enabling improved data processing performance. The PI3101 is the first in a new family of high-density power conversion products, which leverages the company's core strength in power management, silicon integration and system-level packaging. The PI3101 can provide high density power conversion and isolation at the point-of-load, reducing overall solution size while also eliminating an additional conversion stage that degrades overall electrical efficiency. The PI3101 can replace sixteenth bricks or discrete based designs with 50% reduction in total solution area. The Cool-Power family of products will allow the system designer the flexibility to place the required isolated voltage at the point-of-load virtually anywhere it is needed, regardless of topology of the bus architecture, as long as 48V are available.
The Cool-Power family is built on a proprietary ZVS topology using advanced control silicon integration, state of the art planar magnetics and high performance power semiconductor technology enabling switching frequencies in excess of 1MHz. The PI3101 provides the system designer with a simple solution that requires very few external components and achieves up to 87% efficiency. Fast transient response to dynamic loads limits the requirement for output bulk capacitance and EMI performance is significantly improved due to the inherent low noise and high frequency characteristics of the product.
The high density, surface-mount PSiP packaging platform facilitates PCB layout optimization, offers the designer the opportunity to employ a variety of cooling techniques and protects the circuit components against mechanical and ambient factors, thus improving reliability.
The PI3101 is fully equipped with a variety of programmable features including: +/-10% output voltage trimming, programmable soft-start capability, remote on/off ENABLE and an accurate temperature monitor function that provides an analog output voltage proportional to the internal temperature of the product, serving also as a fault alarm. The PI3101 is self-protected against various fault conditions including: input over-voltage and under-voltage lockout with auto-restart capability, over-temperature and output over-voltage protection with auto- restart capability and a dual current limit threshold to protect against short circuits and overload conditions.
"The Cool-Power solution is the first product of its class on the market today that delivers this much power in a footprint that is half the area of a conventional sixteenth brick, enabling 105W per square inch and 400W per cubic inch of power processing. This results in up to 3-4 times the power density of alternate solutions. The technology that is embedded within the Cool-Power platform truly enables a step-function improvement in power conversion density, translating directly into incremental end-system performance," said Carl Smith, Director, Strategic Marketing and Business Development.
The PI3101 is available in a 0.87 inches (l) x 0.65 inches (w) x 0.27 inches (h) surface mountable PSiP package and is available at $29.97 for 1,000-piece quantities. Prices are in US dollars and are subject to change. The PI3101 is sampling now with full production volumes expected by the end of the second quarter of 2010.
