Paralleling of DC/DC converters is often used to increase the output power capability of a single unit by connecting the outputs of two or more converters in parallel. By connecting the parallel pin of each module together, the units will share the load current equally within a few percent. This paper focuses on how N+M redundancy and Hot Plug-in capability can be achieved

Thermal management is an important part of the system design process. This paper presents some guidelines for good thermal design of systems using RO converters.

With the recent acquisition of RO Associates, Astrodyne has expanded its line of DC/DC converters to include the high-reliability, high-density MicroVerter® Series. This series ranges from 200-300 Watts available in ¾ brick. The MicroVerter Series features -40°C to +100°C operation (-55°C optional), current sharing, remote sense, switching frequency synch option, and trimmable output for rugged and extreme applications.

Astrodyne Corporation has acquired the assets of specialty power supply manufacturer RO Associates from Emrise Corporation (ARCA:ERI). RO Associates is an engineering company and a pioneer in the development of module-based power conversion solutions, which are now a mainstay in military, industrial and other harsh environment markets. Current products are deployed on airborne, shipboard and land vehicle applications, as well as a variety of indu...

Counterfeit parts represent a threat to legitimate manufacturers of electronic equipment around the globe and aggressive measures are mandatory if product integrity is a priority. Many of the industry’s best known companies have ended up with these parts without being aware that their well managed supply chain had holes in it. This is a particular problem in the current economic downturn as suppliers have reduced inventories in order to deal ...

Astrodyne has announced the availability of the PWC12, a micro-miniature AC/DC switching power supply with 12 Watt output power. The PWC12 is available in three styles – Open frame, Single-In-Line (SIP) style PCB pin mount and fully Encapsulated PCB pin mount. The compact package sizes begin at 2” x 1” x .67” (50.8 x 25.4 x 17 mm) and are designed to replace more costly and larger discrete designs, all models offer single outputs of 3.3...

Astrodyne has introduced the PMK/PMMK130, the most recent series of flexible switching AC/DC power supplies to join the PMK/PMMK family. The PMK/PMMK family currently consists of 150, 225, 320, 450 W and now has added 130 W for lower wattage applications. This new series provides standard single and triple output voltages of 5, 12, 15, 24, 28, 36 and 48V, enhancing their utility across a wide range of applications. Astrodyne offers the designe...
