Point-of-load DC-DC converter power electronics devices introduced by FDK for limited board-to-board-clearance applications

June 20, 2010
SAN JOSE, Calif., 20 June 2010. FDK Corp. in San Jose, Calif., is introducing three non-isolated, point-of-load (POL) DC-DC converters for high density racks, blade systems, and low profile consumer applications with limited board-to-board and board-to-case clearances. These surface-mount power electronics devices operate from a 3.0 to 5.5 volts DC input bus and deliver as much as 3, 4, and 6 Amperes (A) of output current with efficiencies to 94 percent. 

SAN JOSE, Calif., 20 June 2010. FDK Corp. in San Jose, Calif., is introducing three non-isolated, point-of-load (POL) DC-DC converters for high density racks, blade systems, and low profile consumer applications with densely spaced boards. These surface-mount power electronics devices operate from a 3.0 to 5.5 volts DC input bus and deliver as much as 3, 4, and 6 Amperes (A) of output current with efficiencies to 94 percent.

The board-level power supplies provide a tightly regulated programmable output voltage in the range of 0.8 to 3.465 volts DC and deliver the rated output current with no derating in ambient temperatures as much as 85 degrees Celsius under natural convection, company officials say.

FDK's 3A model FPDK05SR8003PSV, 4A model FPDK05SR8004PSV, and 6A model FPDK05SR8006PSV power/analog electronics devices come in 0.657 by 0.402 SMD packages, and are smaller than 0.3 square inches and 0.134 inches high for the 3A and 4A converters, and 0.173 inches high for the 6A converter.

The DK series single-input converters do not require an external Vcc (bias) supply for operation, have programmable output voltage, remote ON/OFF, over-current and over-temperature protection, a power good signal, and start up into a pre-biased output.

All DK series products are RoHS compliant. For more information contact FDK online at www.fdk.com.
