Convertors claim smaller footprints

Edited by the Electronicstalk editorial team Dec 16, 2005

The SWX series of low power DC/DC convertors includes the world's smallest footprint 30W version.

Aimed at telecomms, mobile communications and networking applications with 48V DC input for onboard power, XP Power's SWX series of low power DC/DC convertors includes the world's smallest footprint 30W version.

The low cost convertors save valuable board space.

The 10-30W SWX series is aimed at optical fibre access equipment, ADSL applications, routers, switches, and cellular basestations where small size, high efficiency, high operating temperatures, low profile and surface mount capability are requirements.

Obviating the need for fans, the convection-cooled convertors have an operating temperature range of -40 to +85C.

Their 91% efficiency ensures that minimal heat is generated, providing increased reliability and simplifying cooling arrangements.

Useful in applications where PCBs are stacked closely, the convertors have a low profile.

The 10, 15 and 20W models have a footprint of 38.7 x 27.2 x 5mm, and the 30W version has a footprint of 38.7 x 31.2 x 8mm.

SWX DC/DC convertors employ synchronous rectification to enhance efficiency.

The input voltage range for 48V models is 36-76V DC, and the 24V input versions accept a voltage input range of 18 to 36V DC.

Output voltages are from 1.2 to 15.0V.

The convertors require no minimum load and all versions feature comprehensive over- and undervoltage protection, overcurrent protection, remote on/off, an alarm signal and parallel operation of up to ten units.
