| FDK Corporation (Tokyo Stock Exchange 1st Section: Code 6955), a global electronic component and battery manufacturer, introduces a new high power regulated quarter brick to its Sensei Series of isolated dc/dc converters. The FPQR48T5R040 converter provides 40 Amperes (A) of output current (200 Watts) with best-in-class thermal performance. This converter 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 5V distribution bus. The FPQR48T5R040 converter operates from a 36Vdc to 75Vdc input and provides a tightly regulated 5Vdc output with an efficiency in excess of 92.5%. It is offered in a 2.30 * 1.45 * 0.555 (58.4mm * 36.8mm * 14.1mm) industry-standard quarter brick footprint and pin-out. As an available option, the FPQR48T01225 converter can support parallel operation of multiple units without the need for external components, with a load sharing accuracy within +/- 10%. 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 FPQR48T5R040 converter meets the basic insulation requirements of EN60950 and features input to output dc isolation of 1500Vdc. The Sensei Series converters require little or no derating at high ambient temperatures without the need for heat sinks. With a 48Vdc input, the FPQR48T5R040 converter delivers the full-rated output of 40A (200W) at ambient temperatures up to 80 degrees Celsius with 400LFM (2.0m/s) airflow, and up to 85 degrees Celsius with 500LFM (2.5m/s) airflow. This leading-edge thermal performance is the result of electrical, thermal, and packaging design that is optimized for high density circuit card conditions, realized using FDK's advanced circuit and thermal design techniques. "The FPQR48T5R040 converter is an important addition to the Sensei Series", said Dr. Apurba Roy, executive advisor, FDK Corporation. "It elevates FDK’s support of 5V distribution rails to the 200W level, while maintaining FDK's signature thermal performance." 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 FPQR48T5R040 converter is priced at $65.00. Samples are available now. For more information, visit our website at http://www.fdk.com/cyber-e/s_ddconv/s_dd_conv.htm or E-mail us at the following locations.
