FDK Low Input Voltage POL Converters Deliver Up To 30A

FDK America, Inc. announced an expansion of its Senpai series of non-isolated point of load (POL) converters with the addition of eight new products comprising the FPMR05T and FPLR05T dc/dc converters. Offered in industry-standard footprints, these converters operate from a 2.4 to 5.5Vdc input bus and provide a tightly-regulated programmable output voltage in the range of 0.75 – 3.63Vdc. At the leading edge for POL converters in these standard sizes and input voltage range, the FPMR05T converters deliver up to 10A of output current, and the FPLR05T converters deliver up to 30A. Little or no derating is needed up to 85°C.

The FPMR05T converters are available in 6, 8, and 10A output current models, in a 0.90 x 0.40 x 0.195" (22.9 x 10.2 x 4.95mm) industry-standard SIP package. The FPLR05T converters are offered in 10, 16, 20, 25, and 30A output current models, in a 2.0 x 0.535 x 0.315" (50.8 x 13.6 x 8.0mm) industry-standard SIP package. 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 dc/dc converters are said to be 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. At an output voltage of 3.3V, the FPMR05T converters deliver up to 10A of output current with no derating in ambient temperatures of up to 85°C under natural convection, and the FPLR05T converters deliver up to 30A with no derating in ambient temperatures of up to 70°C with 400LFM (2m/s) airflow. This excellent thermal performance results from electrical, thermal, and packaging design that is optimized for high density circuit card conditions.

"With the addition of the FPMR05T and the FPLR05T converters to the Senpai series, FDK can now offer a complete line-up of high performance POLs in industry-standard SIP and SMD packages, covering the range up to 30A, for 12V, 5V and 3.3V distribution rails," said Dr. Apurba Roy, Executive Advisor, FDK Corp..

All Senpai series products are RoHS compliant. In quantities of 1,000 pieces, the FPMR05T converters are priced at $6.00, $7.50, and $9.00 for the 6, 8, and 10A models, respectively, and the FPLR05T converters are priced at $10.00, $12.50, $15.00, $17.00 and $19.00 for the 10, 16, 20, 25, and 30A models, respectively.
