FDK presents first in series of DC/DC converters for elevated temperature environments

SAN JOSE, Calif., 29 Jan. 2007. FDK Corporation introduced its Sensei Series of isolated DC/DC converters with the release of the FPQN48T9R632, a 330-watt bus converter in the industry-standard quarter brick format. Sensei Series converters are designed for intermediate bus architecture (IBA) and distributed power architecture (DPA) applications that require high efficiency and high reliability in elevated temperature environments.

SAN JOSE, Calif., 29 Jan. 2007. FDK Corporation introduced its Sensei Series of isolated DC/DC converters with the release of the FPQN48T9R632, a 330-watt bus converter in the industry-standard quarter brick format.

Sensei Series converters are designed for intermediate bus architecture (IBA) and distributed power architecture (DPA) applications that require high efficiency and high reliability in elevated temperature environments. In combination with its Senpai Series of non-isolated point of load (POL) converters, FDK can now provide a complete board-mounted power package for these architectures.

The first product in the Sensei Series, the FPQN48T9R632 is an IBA bus converter that operates from a 36V DC to 55V DC input. It delivers 32 Amperes of output current at a fixed 5:1 ratio step-down output voltage, with an efficiency in excess of 95 percent and a power density of up to 300 watts/cubic inch.

The FPQN48T9R632 converter is offered in a 2.28x1.45-inch (57.9x36.8 mm) industry-standard quarter brick footprint and pin-out. It has a very low body profile of 0.34 of an inch (8.7 mm).

Protection features include input under-voltage lockout (UVLO), output over-current protection (OCP), output over-voltage protection (OVP), and over-temperature protection (OTP). Built-in current sharing enables parallel operation without the need for external circuitry. The FPQN48T9R632 converter meets the basic insulation requirements of EN60950 and features input to output DC isolation of 1500 volts.

All Sensei Series products are RoHS compliant. In quantities of 1000 pieces, the FPQN48T9R632 converters are priced at $42. Samples are available.
