Enpirion 9A Power Supply Sets New Power Density Benchmark

Tag : power inductor
BRIDGEWATER, New Jersey, June 23, 2008 – Enpirion todayannounced the availability of a 9A DC-DC converter that sets a newstandard for power density by delivering over 76 Watts per squareinch (over 11 Watts per square centimeter). The EN5395QI featuresEnpirions proprietary integrated-inductor technology and ultra-highswitching frequency, enabling the PwrSoC (power supply on a chip)to achieve high noise immunity with a very small footprint. Thepart also offers two options for setting the output voltage,providing the utmost flexibility for the user.

Enpirions 9A synchronous buck PWM (pulse-width modulation) DC-DCconverter integrates the inductor, MOSFETS, and controller into a10 x 12 x 1.85 mm package. The part requires as few as fiveexternal MLCC capacitors for a complete power management solution,with a total footprint of 250 sq mm. The EN5395QI delivers up to 30watts of continuous output power, and achieves up to 93 percentefficiency.

“With every new product, Enpirion sets out to deliver maximumpower in a minimal package,” said Dr. Ashraf Lotfi, Enpirionsfounder and CTO. “The 9A part goes beyond this by offeringdesigners the flexibility they need to simplify board layout, addfeatures, and get to market faster.”

In addition to small footprint, low part count, and low noise, theEN5395QI simplifies design as a result of output voltage scaling.Output voltage is programmed using a 3-pin voltage-ID (VID) input,allowing designers to choose one of seven pre-programmed outputvoltages. This allows developers to conserve power by optimizingthe parts output voltage to each specific load requirement. It alsoprovides the flexibility to use the same device for multiplesolutions that require different output voltages. Increasing loadcurrent capacity is also simple – from 2 to 4 devices can beplaced in parallel to provide a single load with up to 36A ofoutput current.

The EN5395QI is a point-of-load power regulator designed to meetthe precise voltage and fast transient requirements of low-powerprocessors and SoCs (system on a chip) used in a variety ofmarkets, including storage, networking, computing, telecom,audio/video, and other distributed power architectures. With itslow-noise PWM topology, the 9A part is ideally suited fornoise-sensitive applications.

Pricing & Availability

The EN5395QI is available now, and pricing is set at $8.10 forquantities of 1000 parts. A datasheet and additional informationare available here: www.enpirion.com/Productdetails.aspx?pid=34
