Tiny 2W converters are for use in medical devices

For use in medical device applications that require safety isolation between the input and output, the IML02 and ISM02 miniature 2W rated DC/DC converters from XP Power provide 4,000V AC reinforced isolation with 1 x MOPP at 300V AC (250V AC model IML02) working voltage. They are aimed at patient connected devices and have a low 2micro A patient leakage current.

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

Their small size, 0.77 x 0.39 x 0.49in for the SIP-7 packaged IML02, and 0.94 x 0.71 x 0.36in for the ISM02, takes up less PCB space, and in both cases allow the product designer more room to add extra features, or alternatively reduce the overall size of the end product, says the company.

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 small footprints, the units are well suited to compact medical devices.

The IML02 is available in four different input voltage ranges for nominal 5.0, 12, 15 or 24V DC inputs, while the ISM02 comes in three ranges for 5.0, 12 and 24V DC input applications. The ISM02 offers single output models of 5.0, 12, 15V, and ±12V and ±15V dual output models, while the IML02 has 3.3, 5.0, 9.0, 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.
