FDK Corp. has expanded its Sensei Series of isolated DC/DC converters with the addition of the FPER48T5R020 and the FPER48T01210 eighth brick converters.

The FPER48T5R020 provides up to 20A of output current (100W) at a regulated voltage of 5V while the FPER48T01210 delivers up to 10A of output current (120W) at a regulated voltage of 12V. They are targeted at Intermediate Bus Architecture and Distributed Power Architecture in telecommunications, WiMAX, data processing, computing and storage applications.

The two converters operate from 36Vdc to 75Vdc input, and are offered in a 2.30-inch x 0.90-inch industry-standard eighth brick footprint and pin-out. They have a low body profile of 0.421-inch, making them particularly suitable for high density card-rack applications.

Standard features include input under-voltage lockout, output overcurrent protection, output over-voltage protection, overtemperature protection, remote output voltage sense and output voltage trim using industry-standard trim equations. The converters meet the basic insulation requirements of EN60950 and feature I/O DC isolation of 1500Vdc.

These Sensei Series converters deliver full-rated output power and current, with little or no derating, at high ambient temperatures without the need for heat sinks. With a 48Vdc input and 400 LFM (2m/s) airflow, the FPER48T5R020 delivers 100W (20A) at ambient temperatures up to 75C, and the FPER48T01210 offers 100W (8.4A) at temperatures up to 75#176;C and 120W (10A) at temperatures up to 55#176;C.
