FDK Adds 10 Amp DC/DC Converters
Small footprint DC/DC converter.
San Jose, CA — FDK Corporation has introduced the latest products in its Senpai Series of non-isolated point of load (POL) converters with the addition of DC/DC converters designed to operate from a 2.4 to 5.5VDC input bus. Delivering up to 10 Amps in the smallest industry-standard footprint, the FPMR05SR75 converters provide up to 67 percent higher output current than other available POL converters in the same input voltage range, and, with a power density of up to 475 Watts/in.{SP3}, 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 converters are offered in 3A, 5A, 6A, 8A, and 10A output current models, in a 0.8 x 0.45 x 0.211-in. (20.3 x 11.4 x 5.35mm) SMD package with industry-standard footprint and pin-out. They provide tightly-regulated programmable output voltages in the range of 0.75V — 3.63VDC. All models have remote ON/OFF, over-current and over- temperature protection, and output voltage adjust, and are compatible with standard trim equations.

According to the manufacturer, the converters deliver full-rated output current, with little or no derating, at high ambient temperatures, with minimal airflow. With a 5.0VDC input and 3.3VDC output, in an ambient of 85°C 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. All Senpai Series products are RoHS compliant.
