Aimed at telecoms, mobile communications and networking applications with48VDC input for onboard power, XP Power¹s SWX series of low power DC/DCconverters includes the world's smallest footprint 30W version.
The lowcost converters save valuable board spaceThe 10 to 30W SWX series is aimed at optical fibre access equipment, ADSL applications, routers, switches, and cellular base stations where smallsize, high efficiency, high operating temperatures, low profile, and surface mount capability are requirements.
Obviating the need for fans, the convection-cooled converters have anoperating temperature range of -40 to +85 degrees C. Their 91% efficiencyensures that minimal heat is generated, providing increased reliability andsimplifying cooling arrangements.
Useful in applications where PCBs are stacked closely, the converters have alow profile. The 10, 15 and 20W models have a footprint of 38.7 x 27.2 x5mm, and the 30W version has a footprint of 38.7 x 31.2 x 8mm.SWX DC/DC converters employ synchronous rectification to enhance efficiency.
The input voltage range for 48V models is 36 76VDC, and the 24V inputversions accept a voltage input range of 18 to 36VDC. Output voltages arefrom 1.2V to 15.0V.
The converters require no minimum load and all versions featurecomprehensive over and low-voltage protection, overcurrent, remote on/off,an alarm signal and parallel operation of up to ten units.
