FDK's Senpai Low Input Voltage POL Converters Deliver up to 30A with Output Voltage Tracking
For Intermediate Bus and Distributed Power Architecture Applications

Dec. 10, 2008


FDK Corporation (Tokyo Stock Exchange 1st Section: Code 6955), a global electronic component and battery manufacturer, announces the addition of eight new dc/dc converters to its Senpai Series of non-isolated point-of-load converters. Operating from a 2.4 Volt - 5.5 Volt (V) DC input bus with a tightly regulated programmable output voltage of 0.75V to 3.63V DC, these converters incorporate an output voltage tracking function that enables various sequenced power-up and power-down scenarios when using multiple converters. The FPMS05T converters deliver up to 10 Amperes (A) of output current and the FPLS05T converters deliver up to 30A. Requiring little or no derating up to 85 degrees Celsius, these converters provide best-in-class thermal performance.

The FPMS05T converters are offered in 6A, 8A, and 10A output current models, in a 1.0 * 0.472 * 0.195 inch (25.4 * 12.0 * 4.95mm) industry-standard SIP package. The FPLS05T converters are offered in 10A, 16A, 20A, 25A, and 30A output current models, in a 2.0 * 0.535 * 0.315 inch (50.8 * 13.6 * 8.0mm) industry-standard SIP package. All models feature remote ON/OFF, over-current and over-temperature protection, and output voltage adjust, and are compatible with standard trim equations. The output voltage tracking function supports three kinds of sequenced start-up and shut-down scenarios: sequential, simultaneous, and ratiometric.

Applications for the Senpai Series of point of load converters include Intermediate Bus Architectures (IBA) and Distributed Power Architectures (DPA) in telecommunications, WiMAX, data processing, networking and computing, storage, and other applications that require high efficiency, tight regulation, and high reliability in elevated temperature environments.

The Sensei Series converters deliver full-rated output power and current with little derating at high ambient temperatures without the need for heat sinks. With a 48Vdc input and 500 LFM (2.5m/s) airflow, the FPQR48T01225 converter delivers 300W (25A) at ambient temperatures up to 60 degrees Celsius and 250W (21A) at temperatures up to 80 degrees Celsius.

"The FPMS05T and the FPLS05T converters combine the industry-leading thermal performance of the standard Senpai Series POLs with a voltage tracking capability", said Dr. Apurba Roy, executive advisor, FDK Corporation. "FDK will continue to expand its dc/dc product line-up to meet the increasingly sophisticated demands of a diverse global customer base."

All Senpai 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 FPMS05T converters are priced at $7.00, $8.00, and $10.00 for the 6A, 8A, and 10A models, respectively, and the FPLS05T converters are priced at $11.00, $14.00, $16.00, $18.00 and $20.00 for the 10A, 16A, 20A, 25A, and 30A models, respectively. Samples are available now.
