Miniature 2 Watt DC-DC converters for use in medical applications now available

XP Power has unveiled the IML02 & ISM02, two miniature 2W rated DC-DC converters for use in medical device applications that require safety isolation between the input and output.

These converters are able to provide 4000 VAC reinforced isolation with 1 x MOPP at 300 VAC (250 VAC model IML02) working voltage and are suitable for use in patient connected devices, and have a very low 2 µA patient leakage current.

Featuring 2W of output power and with both single and dual voltage output models, the converters are available in an SMD package (model ISM02) or a through hole, industry standard SIP7 package (model IML02).

Measuring 19.5 x 9.8 x 12.5 mm for the SIP-7 packaged IML02, and 24.0 x 18.0 x 9.0 mm for the ISM02, they have been designed to take up less PCB space, and in both cases afford the product designer with more room to add extra features, or alternatively reduce the overall size of the end product.

Both converters feature extended operating temperature ranges, -40°C to +85°C for IML02 and -25°C to +105°C for the ISM02.Offering high efficiency, wide operating temperature and very small footprints, the units are well suited to modern compact medical devices.

The converters meet Class B EMI EN55011 standards (conducted EMI requires a small input filter for the IML range) and carry worldwide medical safety approvals to 60601-1 standards.
