FDK Intros Eighth Brick DC/DC Converters
Eighth-brick DC/DC converter.
San Jose, CA — FDK Corporation is introducing the first eighth brick products in its Sensei Series of isolated DC/DC converters — the FPER48T converters that provide 30 A of output current at regulated voltages of 3.3 to 1.2VDC with little or no derating at elevated temperatures. With a 48VDC input and 400 LFM (2m/s) airflow, the converters deliver full-rated output current at ambient temperatures up to 85°C.

The converters are designed for Intermediate Bus Architecture (IBA) and Distributed Power Architecture (DPA) in telecommunications, data processing, computing, and storage applications.

The 30A FPER48T converters operate from a 36 to 75VDC input, and are available in standard output voltages of 3.3, 2.5, 1.8, 1.5 and 1.2V. They are offered in a 2.30 x 0.90-in. (58.4 x 22.8mm) industry-standard eighth brick footprint and pin-out, and have a low body profile of 0.421-in. (10.7mm), making them 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 FPER48T converters meet the basic insulation requirements of EN60950 and have input-to-output DC isolation of 1500V.
