DC/DC converters for space-critical applications

Edited by the Electronicstalk editorial team Oct 23, 2008

The Bel Power division of Bel Fuse has introduced the Micro SIP series of non-isolated DC/DC converters, designed to minimise costs in space-critical applications.

Micro SIP modules operate over a wide input range of 4.5V to 13.8V and an ultra-wide output voltage trim range from 0.59 VDC to 5.1 VDC to minimise the quantity of part numbers required in inventory.

In addition, the fixed switching frequency devices yield high efficiencies up to 91 per cent.

The Micro SIP series includes 3A, 6A, and 10A active-high enable, and true active-high enable, converter modules.

The RoHS EU Directive 2002/95/EC-compliant devices are intended for use in a range of distributed power architectures and POL applications in which components with an especially small footprint and limited height are required.

They are commonly employed in telecommunication and networking equipment, as well as in servers, storage, and datacom applications.

Micro SIP DC/DC converters' control and protection features include differential remote on/off, under-voltage lockout, and over current/short circuit protection.

Devices switch at a fixed frequency of 500 kHz.

Produced in a five-pin SIP configuration, 3A and 10A modules measure 0.65in (l) x 0.41in (w) x 0.32in (h), while 6A modules measure 0.65in (l), 0.41in (w) x 0.295in (h).
