FDK Sensei Series Isolated DC/DC Converter Delivers 18A at 12V with Minimal Derating
Up to 216W of regulated output power for IBA and DPA applications

Aug. 28, 2008


FDK Corporation (Tokyo Stock Exchange 1st Section: Code 6955), a global electronic component and battery manufacturer, introduces a regulated dc/dc converter in the industry-standard quarter brick format that provides 18 amperes (A) (216 Watts) of output current with minimal derating at elevated temperatures. The FPQR48T01218 is the latest in the FDK Sensei Series of isolated dc/dc converters, and is designed for Intermediate Bus Architecture (IBA) and Distributed Power Architecture (DPA) in telecommunications, WiMAX, data processing, computing, and storage applications that require a regulated 12 Volt (V) distribution bus.

The FPQR48T01218 converter operates from a 36Vdc to 75Vdc input and provides a tightly regulated 12Vdc output. It delivers up to 18A with an efficiency in excess of 91%. It has a 2.30 * 1.45 (58.4 * 36.8mm) industry-standard quarter brick footprint and pin-out and a low body profile of 0.402 (10.2mm), particularly suitable for high density card-rack applications.

Standard features include input under-voltage lockout (UVLO), output over-current protection (OCP), output over-voltage protection (OVP), over-temperature protection (OTP), remote output voltage sense, and output voltage trim using industry-standard trim equations. The FPQR48T01218 converter meets the basic insulation requirements of EN60950 and features input to output dc isolation of 1500Vdc.

The Sensei Series converters deliver full-rated output current with little derating at high ambient temperatures without the need for heat sinks. With a 48Vdc input and 400 LFM (2m/s) airflow, the FPQR48T01218 converter delivers 216W (18A) at ambient temperatures up to 60 degrees Celsius and 200W (17A) at temperatures up to 70 degrees Celsius.

"FDK provides high quality on-board power solutions with best-in-class thermal performance at a competitive price", said Dr. Apurba Roy, executive advisor, FDK Corporation. "FDK will continue to expand its line of Sensei Series converters to meet the demands of a growing global customer base."

All Sensei Series products are RoHS compliant. They are manufactured using FDK’s state-of-the-art in-house manufacturing processes and systems in Japan. In quantities of 1,000 pieces, the FPQR48T01218 converter is priced at $47.00. Samples are available now.
