DC/DC converters

XP Power has launched the IM and IT series of 2- and 3W board mounted regulated DC/DC converters. Encapsulated in a plastic non-conductive SIP format package, measuring 26mm x 12.5mm x 9.3mm, the devices offer an extra wide 4:1 input range and an input to output isolation of 1.5kV for up to 1 minute. They are ideal for use in mobile, portable and wireless products where board space is at a premium and designers seek to reduce the size of their end product.

Together the IM series, rated at 2W, and the IT series, rated at 3W, provide a total of 28 variants. Covering the nominal input voltages of 12-, 24- and 48Vdc, each series offers either 9Vdc to 36Vdc or 18Vdc to 75Vdc input ranges. Within each range single and dual output versions are available. Single output models provide 3.3-, 5-, 12 or 15Vdc while the dual output units offer 5-, 12- or 15Vdc. All outputs are fully regulated to within 0.5 percent over all input conditions and to less than 0.5 percent over all load conditions from 10 to 100 percent load. A remote on/off function allows an external signal to control the converter.

The units can operate, without any additional heat sinking or forced airflow, from -40C to +100C. Full power output is available up to +75C and with derating up to the maximum case temperature of +100C. These highly reliable DC/DC converters have an MTBF in excess of 1.2 million hours as defined by MIL-HDBK-217F calculations.

Prices range from $12.87 each for a 500-piece order of the single output IM series to $18.72 for a 500-piece order of the dual output IT series.
