SMD DC-DC Converters Offer Increased Efficiency, Isolation and Temperature Range

XP Power announces six new series of high performance isolated DC-DC converters in industry standard SMD packages. Offered in single and dual output versions the compact 'next generation' devices are available in power ranges from 0.25 to 3 Watts. They have a higher efficiency, increased isolation and an extended operating temperature range compared to existing competitive models in the market.

Both regulated and unregulated output models are available.  The ISA, ISE, ISH and ISK series offer unregulated outputs while the ISR and ISW have regulated outputs.  Exhibiting versatility, the ISE and ISA ranges provide 1W of output power with single and dual unregulated outputs respectively, the ISH is a 2W version of the ISE range, and the ISK offers an unregulated 0.25 Watt single output. In addition the ISW is a 1W single output converter with a regulated output, with the ISR range providing a regulated 3 Watt single output.  Accordingly there are various combinations of single output models from 3.3 to 24VDC, and dual output models with outputs of ±5, ±9, ±12, ±15 and ±24VDC. Each series offers up to five ±10% input voltage ranges or a 2:1 input range on the ISR series.

Offering standard 1,500 or optional 3,000 VDC input / output isolation figures, the converters measure just 0.50 x 0.327 x 0.285" (12.7 x 8.3 x 7.25 mm) for the ISE, ISH and ISK ranges.   The ISA and ISW measure 0.60 x 0.327 x 0.285" (15.24 x 8.30 x 7.25 mm) and the ISR measures 0.94 x 0.54 x 0.31" (23.86 x 13.70 x 8.00 mm).  All have industry standard pin outs. The converters' small size takes up less PCB space allowing designers more room to add extra features, or alternatively to reduce the size of their end product.

The DC-DC converters feature an extended operating temperature range of -40 to +105 degrees C for the ISA, ISE, ISH, ISK and ISR ranges (+85 °C for ISW), and full output power up to +100 °C is achievable (+85 °C for ISR and +70 °C for ISW).

The versatile ISA/E/H/K/R/W DC-DC converter ranges from XP Power are suitable for use in application areas including automation and process control, broadcast, instrumentation, mobile communications, and other compact electronic equipment.

The ISA/E/H/K/R/W series is priced at $3.71 for 500 pcs orders of the ISA model and is available from Newark, Digi-Key, or direct from XP Power and come with a 3 year warranty.
