Latest 1W DC-DC converters offer a wider temperature range and more isolation

XP Power has introduced three new SIP packaged 1W DC-DC converters available as single- and dual-output models. Aimed at applications requiring a high-performance DC-DC converter, the products feature industry standard pinouts and offer an increased efficiency, higher isolation, and a wider operating temperature range than previous products. The ITA, ITB and ITV series converters provide an unregulated output in a small, industry standard, plastic cased SIP-7 package, allowing drop in replacement capability for improved performance without redesign. ITA and ITB series converters feature 1,500VDC input / output isolation, with the ITV offering an isolation of 3,000VDC. With their small size, the most important application areas for the converters are in mobile, portable and wireless products or indeed when isolation or DC-DC voltage conversion is needed in any product. Such products are used in automation and process control, broadcast, fixed telecom, instrumentation, networking / datacom / computing, mobile comms and transport industries. Measuring just 19.5mm x 6mm x 10mm, the converters offer an attractive power density of 14W per cubic inch. They take up less PCB space allowing designers more room to add extra features, alternatively they can reduce the overall size of the end product. Raising the bar, the natural convection-cooled converters offer an extended operating temperature range of -40C to +105C, providing full output power to +95C and offer considerable advantages over many competitor models that only operate up to +85C. An improved efficiency figure of 80% is well suited to modern, ‘green standard’ end products, meaning a reduction in waste heat and no need for a heatsink. Exhibiting versatility, three input voltage ranges of 5, 12, and 24 VDC are available in each series, and a +/-10% input range capability covers nominal 5,12 and 24VDC applications. The ITB series has single outputs of 5V, 12V and 15V. ITA has +/-5V, +/-12V and +/-15V duals output models, while ITV comprises both single and dual output models. The converters meet Class B EMI standards with the addition of a small two component input filter. Employing the latest technology, XP Power’s ITA, ITB and ITV DC-DC converters are next generation, unregulated 1W converters with a SIP-7 footprint. They have high efficiency, increased isolation, and an extended operating temperature range in an industry standard SIP package.
