FPER48T

FDK Corp. has announced the FPER48T converters, the first eighth brick products in the company's Sensei series of isolated DC/DC converters. The new converters provide 30A output current at regulated voltages of 3.3-1.2V with little or no derating at elevated temperatures. With a 48Vdc input and 400 LFM (2m/s) airflow, the FPER48T converters deliver full-rated output current at ambient temperatures up to 75C and 85C at output voltages of 3.3V and 1.2V, respectively, without the need for heat sinks. These 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 of the Sensei series operate from a 36Vdc 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 58.4mm x 22.8mm industry-standard eighth brick footprint and pin-out, and have a low body profile of 10.7mm, making them particularly suitable for high density card-rack applications.

Standard features include input undervoltage lockout (UVLO), output overcurrent protection (OCP), output overvoltage protection (OVP), overtemperature 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 feature input to output DC isolation of 1500V.

"FDK's leading-edge thermal performance results from electrical, thermal and packaging design that is optimized for high density circuit card conditions using advanced circuit and thermal design techniques," said Apurba Roy, executive advisor, FDK Corp. "With the addition of the 30A FPER48T converters to the Sensei series, FDK can now provide high-performance solutions for isolated output voltages in the range from 12V to 1.2V for IBA and DPA applications."

All Sensei series products are RoHS-compliant. They are manufactured using FDK's in-house manufacturing processes and systems in Japan. In quantities of 1,000 pieces, the 30A FPER48T converters are priced at $37. Samples are available.
