FDK Isolated DC-DC Converter Delivers 200W At 80°C With No Derating
FDK Corp. introduced a new high power regulated quarter brick to its Sensei Series of isolated dc-dc converters. The FPQR48T5R040 converter provides 40A of output current (200W) 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 36 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 x 1.45 x 0.555" (58.4 x 36.8 x 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°C 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 Corp.. "It elevates FDK’s support of 5V distribution rails to the 200W level, while maintaining FDK’s signature thermal performance."
In quantities of 1,000 pieces, the FPQR48T5R040 converter is priced at $65.00.
