DC/DC convertors survive with minimal cooling

The FPMR05SR75 10A Senpai DC/DC convertors provide tightly-regulated programmable output voltages in the range of 0.75 to 3.63V DC.

FDK has released Senpai's latest nonisolated point of load (POL) convertors, DC/DC convertors designed to operate from a 2.4 to 5.5V DC input bus.

The FPMR05SR75 10A Senpai convertors provide up to 67% higher output current than other POL convertors in the same input voltage range.

These DC/DC convertors 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 convertors are offered in 3, 5, 6, 8 and 10A output current models, in a 20.3 x 11.4 x 5.35mm SMD package with an industry-standard footprint and pin-out.

They provide tightly-regulated programmable output voltages in the range of 0.75 to 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.

The convertors 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 85C 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 optimised for high-density circuit card conditions.
