Small footprint for high-efficiency switchers

Edited by the Electronicstalk editorial team Sep 28, 2004

The IFC165 is a 165W open-frame AC/DC switching power supply in a 76 x 127 x 32mm package.

The IFC165 is a 165W open-frame AC/DC switching power supply in a 76 x 127 x 32mm package.

With power density of 8.8W/in3, this ultracompact power supply fits into a 1U chassis, making it ideal for space-constrained applications in telecommunications, industrial automation, networking and datacomms.

Its 85 to 90% efficiency, depending on version, saves energy, reduces heat generation and improves system reliability while minimising the need for cooling.

Full power is delivered with just 340 litre/min airflow.

The IFC165 is available in single-, triple- and quad-output versions with output voltages from 3.3 to 48V DC and it has a universal AC input of 90 to 264V.

This innovative switcher has built-in overvoltage, overcurrent and over-temperature protection, and integral power fail detection.

It features maximum ripple and noise of +/-1% or 50mV (whichever is greater) and line and load regulation of +/-3% on all single-output models.

A remote sense function compensates for up to a 0.5V drop at the load.

All single-output models also include an auxiliary 12V/1A output and offer single wire current sharing with ORing diodes.

The IFC165 operates in ambient temperatures from -25 to +70C delivering full output at up to +50C and 82.5W output at +70C.

It meets all major international safety and EMI/EMC specifications.
