FDK: Sensei Series Isolated DC/DC Converter
DC-DC converter.
San Jose, CA — FDK Corporation has introduced a regulated DC/DC converter in the industry-standard quarter brick format that provides 18A (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.

The converter is also well suited for use in WiMAX, data processing, computing, and storage applications that require a regulated 12V distribution bus.

The converter operates from a 36 to 75VDC input and provides a tightly regulated 12VDC output. It delivers up to 18A with an efficiency in excess of 91 percent. It has a 2.30 x 1.45-in. (58.4 x 36.8mm) industry-standard quarter brick footprint and pin-out and a low body profile of 0.402-in. (10.2mm). The converter is 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. According to the company, the 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°C and 200W (17A) at temperatures up to 70°C.
