ISF, ISG and ISL DC/DC converters

XP Power has launched the ISF, ISG and ISL series of low-cost miniature surface mount DC/DC converters. The ISF and ISG 1W series measure just 15.24m x 11.2mm x 6.5mm. Together with the slightly larger 1.5W ISL model, these ultracompact devices take up the minimum of board space allowing designers to reduce the size of their applications. Also, with their industry standard pin out, they are suitable as a drop-in replacement for existing designs. The ISF & ISG models are available with alternative pin out and package configurations to order.

The ISG family provide a single regulated output, covering the nominal voltages of +5-, +12- or +15Vdc. Two variants provide for either +5Vdc or +12Vdc inputs.

Both the ISF and ISL models provide single and dual output versions covering the popular nominal voltages from +3.3Vdc to +15Vdc. The ISF family offer +3.3-, +5-, +12- or +15Vdc input voltage variants. Accommodating an ultrawide 4:1 voltage input range, the ISL series are available in +24- or +48Vdc models. The outputs of the ISG and ISL models are regulated within 1 percent over all load conditions while the ISF series is unregulated.

All IS models provide input to output isolation of at least 1kV. An optional 3kV isolation rating can be specified when ordering any ISF model.

With an extremely wide range of operating temperature, from -40C to +85C, the IS product family are suited to most environments. They can provide full output power, without the need for any forced airflow, up to +70C.

These highly reliable DC/DC converters offer an MTBF in excess of 1 million hours, with the ISF and ISG models being rated greater than 3.5 million hours. All have a three-year warranty.

The ISx series is available from Newark or direct from XP Power for immediate delivery. Pricing starts from $4.29 in medium volumes.
