FDK Introduces 3A, 4A, and 6A High Density, Low Profile POL Converters with Output Voltage Tracking
For high density racks, blade systems, and low profile consumer applications.
San Jose, CA and Tokyo, Japan - June 17, 2009 - FDK Corporation (Tokyo Stock Exchange 1st Section: Code 6955), a global electronic component and battery manufacturer, expands its DK Series with three new non-isolated, point-of-load (POL), dc-dc converters. These very small, low profile surface mount devices deliver up to 6 Amperes (A) of output current at power densities up to 860 watts/cubic inch, with efficiencies up to 93%. Operating from a 5.6Vdc to 14.0Vdc input bus with a tightly regulated programmable output voltage of 0.8Vdc to 6.6Vdc, these new DK Series converters incorporate an output voltage tracking function. They fit a wide range of telecommunications, 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. Under natural convection, the 3A and 4A converters deliver the full rated output current with no derating in ambient temperatures up to 85 degrees Celsius while the 6A converter delivers full rated output current with no derating up to 80 degrees Celsius. The FPDK12SR8003PSS (3A), FPDK12SR8004PSS (4A), and FPDK12SR8006PSS (6A) converters come in a 0.657" x 0.402" (16.7 x 10.2mm) SMD package. Occupying a 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 0.134" (3.4mm), for the 3A and 4A converters, and 0.173" (4.4mm), for the 6A converter, makes them particularly suitable for high density racks, blade systems, and low profile consumer applications. These DK Series 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.
"These new POL converters enhance the electrical functionality of the DK Series while preserving leading-edge thermal performance," said Dr. Apurba Roy, executive advisor, FDK Corporation. "FDK will continue to expand this line of high performance, high density, and cost-effective single component power solutions."
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 FPDK12SR8003PSS is priced at $5.00, the FPDK12SR8004PSS at $5.50, and the FPDK12SR8006PSS is priced at $6.10. Lead time is 8 weeks. Samples are available now.
