The Bel Power Division of Bel Fuse (News - Alert), Inc. reportedly has launched a Micro SIP series of non-isolated DC/DC converters, including the VRAE-031A0, pictured below right.

 

This Jersey City, New Jersey-based company’s series is designed to reduce costs in space-critical applications, according to Bel, which deals in the design, manufacture and sale of products used in networking, telecommunications, high-speed data transmission and consumer electronics.

 

Micro SIP modules operate over an input range of 4.5 to 13.8 volts and an ultra-wide output voltage range of 0.59 Vdc to 5.1 Vdc.  This is done to minimize the quantity of part numbers required in inventory, Bel officials say. The fixed switching frequency devices yield high efficiencies up to 91 percent.

 

The Micro SIP Series includes 3A, 6A, and 10A active-high enable, and true active-high enable converter modules that comply with RoHS EU Directive 2002/95/EC. The devices are ideal for distributed power architectures and POL applications in which components with small footprint and limited height are required. These devices are also being used in telecommunications and networking equipment, servers, storage and datacom applications.

 

The Bel VRAE-03E1A0, pictured right, is part of the series. The module uses a SIP package and its maximum output current of 3A and maximum output power of 15 watts.

 

The control and protection features of Micro SIP DC-DC converters include differential remote on/off, under-voltage lockout, and over current/short circuit protection. Devices switch at a fixed frequency of 500 kHz. The modules are produced in a 5-pin SIP configuration. The Micro SIP Series of non-isolated DC/DC converters are priced at $3.95, $4.15, and $4.75 for the 3A, 6A, and 10A models, respectively, in quantities of 10,000.

 

The main features of the series include: non-isolated; high efficiency; fixed frequency; low cost; wide Input; under-voltage lockout; wide trim; OCP (News - Alert)/SCP; and remote on/off.
