FDK Corporation extends its DK Series with three new non-isolated, point-of-load (POL) dc-dc converters that operate from a 3.0Vdc to 5.5Vdc input bus. These very small, low profile surface mount devices deliver up to 3, 4, and 6 Amperes (A) of output current with efficiencies up to 94%. They provide a tightly regulated programmable output voltage in the range of 0.8Vdc to 3.465Vdc and deliver the full rated output current with no derating in ambient temperatures up to 85 degrees Celsius under natural convection.
FDKs 3A model FPDK05SR8003PSV, 4A model FPDK05SR8004PSV, and 6A model FPDK05SR8006PSV are offered in a 0.657” x 0.402” (16.7 x 10.2mm) SMD package. Occupying a footprint of less than 0.3 in2 (2cm2), they provide 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 with limited board-to-board and board-to-case clearances.

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. They 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. 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.

“These new POL converters bring the leading-edge electrical and thermal performance of the DK Series to 3.3V and 5V distribution rails, expanding the options available for cost-effective single component power solutions” said Dr. Apurba Roy, executive advisor, FDK Corporation. “FDK will continue to add to this exciting segment of its DC-DC converter product line.”
