1W DC-DC converters boost isolation levels

April 23, 2015 // By Graham Prophet
Three SIP packaged 1-Watt DC-DC converters come in both single and dual output models. 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 1,500 VDC input / output isolation, with the ITV offering an isolation of 3,000VDC.

Application areas for the converters are in mobile, portable and wireless products or when isolation or DC-DC voltage conversion is needed in any product. Measurements of 19.5 x 6.0 x 10.0 mm represent a power density of 14 W/in ³. The natural convection cooled converters offer an extended operating temperature range of -40 to +105C, providing full output power to +95C, an advantage over models that only operate up to +85 degrees C. They have an improved efficiency figure of 80%.

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.
