Miniature DC/DC Converters Offer a Choice of SMD Package Options

XP Power announced the availability of its ISF, ISG and ISL series of low cost miniature surface mount DC/DC converters. The ISF and ISG 1 Watt series measure just 0.60 x 0.44 x 0.25 inches (15.24 x 11.2 x 6.5 mm). Together with the slightly larger 1.5 Watt ISL model, these ultra compact 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 ideal 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 +15 VDC. Two variants provide for either +5 or +12 VDC inputs. Both the ISF and ISL models provide single and dual output versions covering the popular nominal voltages from +3.3 to +15 VDC. The ISF family offer +3.3, +5, +12 or +15 VDC input voltage variants. Accommodating an ultra wide 4:1 voltage input range, the ISL series are available in +24 or +48 VDC models.

The outputs of the ISG and ISL models are regulated within +/-1% 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 -40 °C to +85 °C, the IS product family are suited to most environments. They can provide full output power, without the need for any forced airflow, up to +70 °C.

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