Artesyn launches 48V-output DC-DC converter module supporting GaN power amplifier systems

Artesyn Embedded Technologies of Tempe, AZ, USA (formerly Emerson Network Power’s Embedded Computing & Power business), which designs and manufactures power conversion and embedded computing solutions for communications, computing, medical, military, aerospace and industrial applications, has announced its highest-power-output dc-dc converter module.

Housed in a full-brick format, the AGF800 series offers typical efficiency of more than 94.5% and a wide input range of 36-75V. A 48V model (AGF800-48S48) is designed to support the rapidly growing number of high-power wireless base-station (BTS) deployments using gallium nitride (GaN) technology for increased power density and higher efficiency. The 48V model can deliver up to 16.7A output current, while the 28V model can deliver up to 28.6A output current.

An aluminium base-plate structure gives AGF800 series modules excellent thermal performance. Both models can operate between -40oC and +85oC ambient temperature, and can continue to operate at full power up to 100oC base-plate temperature – all without air cooling.

The AGF800 series dc-dc converter modules also offer a wide trim range of 24-53V for the nominal 48V output version and 14-33V for the nominal 24V output version.

Other features include remote enable, remote output sense, trim, auxiliary output, power-good signal; and protection features such as input under-voltage lockout, output over-current protection, output over-voltage protection, and over-temperature protection. No minimum load requirement helps to increase reliability and contributes to a mean time before failure (MTBF) of 1 million hours (calculated according to Telcordia SR-332-2006).
