FDK intros 8A high density, low profile mini POL converters

SAN JOSE, USA & TOKYO, JAPAN: FDK Corp. a global electronic component and battery manufacturer, has expanded its DK Series with two new non-isolated, point-of-load (POL), DC-DC converters.

These very small, low profile surface mount devices (SMD) deliver up to 8 Amperes (A) of output current at power densities up to 1150 watts/cubic inch, with efficiencies up to 93 percent. They operate from a 5.6Vdc to 14.0Vdc input bus with a tightly regulated, programmable output voltage of 0.8Vdc to 6.6Vdc. They fit a wide range of telecom, data communications, computing, industrial, and consumer applications where board space, cost, profile, efficiency, and reliable operation in elevated temperature environments are critical.

The DK Series converters provide complete power conversion solutions without the need for external input and output capacitors. They are true single input converters in that they do not require an external Vcc (bias) supply for operation. At an output voltage of 3.3Vdc, the 8A converters deliver the full rated output current with no derating in ambient temperatures up to 60 degrees Celsius with 400LFM (2m/s) airflow.

The FPDK12SR8008PSV and the FPDK12SR8008PSS converters feature programmable output voltage, remote ON/OFF, over-current and over-temperature protection, a power good signal, and start up into a pre-biased output. The FPDK12SR8008PSS converter additionally incorporates an output voltage tracking function. These converters come in a 0.657” x 0.402” (16.7 x 10.2mm) SMD package. Occupying an SMD footprint of less than 0.3in2 (2cm2), they offer significant space savings over discrete on-board solutions at a competitive price. Their low height of 0.173” (4.4mm) makes them particularly suitable for high density racks, blade systems, and low profile consumer applications.

“These new 8A converters are a significant addition to FDK’s POL line-up, achieving new thresholds in power density,” said Dr. Apurba Roy, executive advisor, FDK Corporation. “Taking the DK Series to the 50W level showcases FDK’s ability to successfully combine high-density assembly process technology with electrical and thermal design expertise to bring leading-edge solutions to the global POL market.”

All DK Series products are RoHS compliant. They are manufactured using FDK’s state-of-the-art in-house manufacturing processes and systems in Japan. In quantities of 1,000 pieces, the FPDK12SR8008PSV and the FPDK12SR8008PSS are priced at $6.20. Lead time is eight weeks. Samples are available now.
