3/6/15W DC/DC converters exceed medical device specifications

March 18, 2016 // By Graham Prophet
XP Power’s JHL & JHM series of encapsulated, isolated and regulated DC-DC converters for medical applications offer 2 x MOPP and patient leakage to 2 µA.

Available with single and dual outputs, the 3W JHL03, the 6W JHL06 and the 15W JHM15, are all packaged in industry-standard format cases ranging from an industry standard DIP-24 for the JHL03 and JHL06 through to 40.6 x 25.4 x 10.2 mm for the JHM15 series.


All models are approved to the 3rd edition international medical safety standards EN60601-1:2006 and ANSI/AAMI ES60601-1:2005, feature 2 µA maximum patient leakage current, and offer 2 x means of patient protection (2 x MOPP). They also have a double / reinforced isolation barrier that provides 4000 VAC maximum input to output isolation for one minute with a 250 VAC working voltage.


The JHL03 and JHL06 series single output models are available with 5, 12 or 15 VDC and duals ±12 or ±15 VDC. Two input range variants are available across the JHL series, 10 – 17 or 20 – 30 VDC, accommodating nominal 12 or 24 VDC applications. The JHM15 series comprises two 2:1 input voltage range options of 9 – 18 or 18 – 36 VDC. Singles provide 5, 12, or 15 VDC and duals ± 5, ± 12 or ± 15 VDC models.


The units meet the EN55011 Level A EMI standard for both conducted and radiated emissions without the need for any external filtering components. Typical applications include medical devices that require a low power isolated and regulated DC-DC converter that has an extremely low patient leakage current and reinforced insulation. The units are in distribution at Farnell, element14, and Digi-Key.
