|
FDK Corporation (Tokyo Stock Exchange 1st Section: Code 6955) introduced
the first regulated products in its Sensei Series of isolated dc/dc converters
with the announcement of the FPQR48T01215 and FPQR48T01214 converters in
the industry-standard quarter brick format. Providing up to 180W of output
power with minimal derating at elevated temperatures, these converters
are designed for Intermediate Bus Architecture (IBA) and Distributed Power
Architecture (DPA) in telecommunications, data processing, computing, and
storage applications that require a regulated 12V distribution bus.
The FPQR48T01215 and FPQR48T01214 converters of the Sensei Series operate
from 36Vdc to 75Vdc and 36Vdc to 65Vdc input, respectively, and provide
a tightly regulated 12Vdc output. They deliver up to 15A and 14A, with
efficiencies in excess of 91%. They are offered in a 2.30" x 1.45"
(58.4 x 36.8mm) industry-standard quarter brick footprint and pin-out with
low body profiles. The FPQR48T01214 converter, with a very low profile
of 0.36" (9.2mm), is particularly suitable for high density card-rack
applications where available clearances can go down to 0.39" (10mm).
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 FPQR48T01214 and FPQR48T01215
converters meet the basic insulation requirements of EN60950 and feature
input to output dc isolation of 1500Vdc.
The Sensei Series converters deliver full-rated output current, with little
or no derating, at high ambient temperatures without the need for heat
sinks. With a 48V DC input, the converters provide 15A and 14A of output
current in ambient temperatures up to 60 degrees Celsius with 400 LFM (2m/s)
airflow. This leading-edge thermal performance results from electrical,
thermal, and packaging design that is optimized for high density circuit
card conditions, realized using FDK's advanced circuit and thermal design
techniques.
"With the introduction of these first regulated converters of the
Sensei Series, FDK can now provide both regulated and non-regulated power
distribution solutions for IBA applications," said Dr. Apurba Roy,
executive advisor, FDK Corporation. "FDK will continue to expand this
series, with new low output-voltage products to be introduced soon."
All Sensei Series products are RoHS compliant. They are manufactured using
FDK's state of the art in-house manufacturing processes and systems in
Japan. In quantities of 1,000 pieces, the FPQR48T01215 and FPQR48T01214
converters are priced at $47.00. Samples are available now.
