FDK's new non-isolated POL converters

FDK Corp. has added two new high performance DC/DC converters to its Senpai Series of non-isolated point-of-load (POL) converters.

The FPMR12TR7510 converter operates from a 6-14Vdc input bus, and delivers up to 10A in the smallest industry-standard footprint, providing up to 67 percent higher output current than other available POL converters in the same input voltage range.

The device features a power density of up to 780W/inch3, which sets a new standard for power delivery in this footprint and pin-out. FPLR05SR7525 converters operate from a 3-5.5Vdc input bus, and delivers up to 25A in the next smallest industry-standard footprint, providing up to 25 percent higher output current than other available POL converters in the same size and input voltage range.

The FPMR12TR7510 converter is offered in a 0.9-by-0.4-by-0.195-inch (22.9-by-10.2-by-4.95mm) industry-standard SIP package and provides a tightly-regulated programmable output voltage in the range of 0.75-5.5Vdc.

FPLR05SR7525 comes in a 1.30-by-0.53-by-0.327-inch (33-by-13.4-by-8.3mm) SMD package with industry-standard footprint and pin-out and provides a tightly-regulated programmable output voltage in the range of 0.75-3.63Vdc DC. Both models feature remote ON/OFF, over-current and over-temperature protection and output voltage adjust, and are compatible with standard trim equations.

The RoHS-compliant Senpai Series 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. Both FPMR12TR7510 and FPLR05SR7525 converters deliver full-rated output current with no derating in ambient temperatures of up to 60C and 70C, respectively, with 400LFM (2m/s) airflow. This leading-edge thermal performance results from electrical, thermal and packaging design that is optimized for high-density circuit card conditions.

The FPMR12TR7510 and FPLR05SR7525 converters are priced at $9.50 and $18, respectively, in 1,000-piece quantities. Samples are available now.
