| FDK Corporation (Tokyo Stock Exchange 1st Section: Code 6955) announced the latest products in the Senpai Series of non-isolated point of load (POL) converters with the addition of dc/dc converters designed to operate from a 2.4 Volt -5.5Volt (V) DC input bus. Delivering up to 10 Amperes (A) in the smallest industry-standard footprint, the FPMR05SR75 Senpai Series converters provide up to 67% higher output current than other available POL converters in the same input voltage range, and, with a power density of up to 475 Watts/cubic inch, set a new standard for power delivery in this footprint and range. These dc/dc converters are designed for Intermediate Bus Architecture (IBA) and Distributed Power Architecture (DPA) applications that require high efficiency, tight regulation, and high reliability in elevated temperature environments with low airflow. The FPMR05SR75 Senpai Series converters are offered in 3A, 5A, 6A, 8A, and 10A output current models, in a 0.8x0.45x0.211 inch (20.3x11.4x5.35mm) SMD package with industry-standard footprint and pin-out. They provide tightly-regulated programmable output voltages in the range of 0.75V -3.63V DC. All models feature remote ON/OFF, over-current and over-temperature protection, and output voltage adjust, and are compatible with standard trim equations. These Senpai Series converters deliver full-rated output current, with little or no derating, at high ambient temperatures, with minimal airflow. With a 5.0V DC input and 3.3V DC output, in an ambient of 85 degrees Celsius with natural convection cooling, the 3A to 8A models provide full-rated current, and the 10A model provides 9A. This best-in-class thermal performance results from electrical, thermal, and packaging design that is optimized for high density circuit card conditions. "FDK has once again raised the bar for point of load power delivery with the introduction of the FPMR05SR75 converters of the Senpai Series," said Dr. Apurba Roy, Executive Advisor, FDK Corporation. "FDK will continue to expand its presence in IBA power, offering high performance, high quality products at competitive prices." All Senpai Series products are RoHS compliant. They are manufactured using FDK's state-of-the-art in-house manufacturing processes and systems. In quantities of 1,000 pieces, the 3A, 5A, 6A, 8A, and 10A models are priced at $4.50, $6.00, $6.50, $8.00, and $9.50, respectively. Samples are available now.
