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

These converters provide 4000 VAC reinforced isolation with 1 x MOPP at 300 VAC (250 VAC model IML02) working voltage and, ideal for use in patient connected devices, 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).

The converters’ small size, only 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, takes 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 to +85 degrees C for IML02 and -25 to +105 degrees 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 IML02 is available in four different input voltage ranges for nominal 5, 12,15 or 24VDC inputs, while the ISM02 is available in three ranges for 5, 12 and 24VDC input applications. The ISM02 offers single output models of 5, 12, 15V, and +/-12V and +/-15V dual output models, while the IML02 has 3.3, 5, 9, 12, 15V and +\- dual versions of each voltage.

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.  XP Power’s new medical 2 Watt DC-DC converters offer the latest technology and with their market leading extended operating range, excellent efficiency and compact dimensions, are their ‘next generation’ converters for medical device applications.
