DC/DC converters suit intermediate bus, distributed power architectures

Three DC/DC converters have been added to FDK Corp.'s Senpai series of non-isolated point-of-load (POL) converters. These converters operate from a 6-14Vdc input bus, and are offered in industry-standard footprints.

Delivering up to 165W of output power, the 30A FPLR12TR7530 converter promises leading-edge performance for POL converters in this standard size and input voltage range. The FPLR12TR7525 and FPLR12SR7525 converters deliver up to 25A with high thermal performance.

All models provide a tightly-regulated programmable output voltage in the range of 0.75-5.5Vdc and feature remote ON/OFF, overcurrent and overtemperature protection, and output voltage adjust and are compatible with standard trim equations.

Apt architecture
These Senpai series DC/DC converters are designed for intermediate bus architecture and distributed power architecture applications that require high efficiency, tight regulation, and high reliability in elevated temperature environments. At an output voltage of 5V, with 400LFM (2m/s) airflow, the FPLR12TR7525 converter delivers full-rated output current with no derating in ambient temperatures of up to 75°C, and the FPLR12TR7530 and the FPLR12SR7525 converters deliver full-rated output current at temperatures of up to 50°C. This thermal performance results from electrical, thermal, and packaging design that is optimized for high density circuit card conditions.

"These new Senpai Series products are a timely extension to FDK's POL lineup," said Apurba Roy, executive advisor to FDK. "FDK continues its mission of providing high quality, cost effective IBA power products at the leading edge of performance."

All Senpai Series products are RoHS compliant. They are manufactured using FDK's state-of-the-art in-house manufacturing processes and systems in Japan.
