DC/DC converters for surface mount applications

Three ranges of surface mount (SMD) DC/DC converters rated at 1, 3 and 6W of output power with single and dual outputs have been unveiled by XP Power. According to the company, the converters offer higher efficiency and extended operating temperature range when compared to existing models.

Aimed at board mounted designs in mobile, telecom, portable and battery powered systems that need small SMD components and require isolation and regulation between the input and output, the converters are claimed to offer an isolation voltage of 1500V DC.

The ISB series provides 1W of output power, the ISC, 3W, and the ISX is a 6W converter. The converters are said to take up less PCB space, giving designers more room to add extra features or to reduce the overall size of their end product. The ISB measures 18.9 x 17.2 x 8.7mm, the ISC, 24.00 x 18.10 x 8.25 mm, and the ISX comes at 25.4 x 22.0 x 10.2mm. The ISC and ISX series operate over temperatures ranging from -40 to 100°C, while the ISB is rated from -40 to 95°C.

Offering 4:1 and 2:1 input voltage ranges, the converters are suitable for applications with inputs ranging from 5 to 75V DC. Comprising single and dual output models for versatility, various combinations of single output models from 3.3 to 24V DC and dual output models with ±5, ±9, ±12, ±15 and ±24V DC are available.
