Artesyn Technologies has launched a new family of surface-mount DC-DC converters that produce up to 50 W of output power from a quarter-brick open-frame package that is only 10 mm high. The SXQ50 series converters employ fixed-frequency switching technology to maximise conversion efficiency. This results in very low internal power dissipation and high reliability.
The first four models in the series are available with 5,0, 3,3, 2,5 or 1,8 V outputs - which can be trimmed from 90 to 110% of nominal - and are capable of delivering very high currents. The 1,8 V and 2,5 V units are rated at up to 20 A, the 3,3 V unit at 15 A, and the 5,0 V model - which has a conversion efficiency of 90% - can deliver up to 10 A. All SXQ50 series DC-DC converters feature a wide input voltage range of 33 to 75 V, making them particularly suitable for systems employing a 48 V distributed power architecture, including any that operate from a -48 V central office battery plant.
The converters have an industry-standard quarter-brick footprint of 58 x 37 mm and are based on an open-frame, single-board design. Low profile also means that rack-mounted systems can employ tighter inter-board spacings. Artesyn has also specifically designed the layout of the converters' input/output connections to match some of the other leading quarter-brick converters on the market - including the company's own EXQ50 series of 50 W throughhole mounting converters - thereby addressing manufacturers' needs to secure a second source option.
The SXQ50 series DC-DC converters have a wide operational temperature range, spanning from -40 to +90°C ambient. They feature a 1500 V d.c. isolation rating and carry a full set of international safety approvals.
