Medical grade DC-DC converters

19 August 2009 Power Electronics / Power Management

XP Power has released the JHM series of compact low-power isolated DC-DC converters. Offering 3 and 6 W board-mounted variants and packaged in an industry standard 24-pin DIP package, the converters conform to the international medical equipment safety standards UL/IEC 60601-1 and CSA-C22.2 No 601.1.

The units provide 3000 V a.c. input to output isolation for up to 1 minute, meeting the secondary isolation requirements for BF and CF applications and 5000 V a.c. isolation up to 10 milliseconds for defibrillation proof compliance. Any medical appliance that may involve patient contact needs to provide isolation from hazardous voltages and have low leakage current. With a small leakage current of 2 μA, and low 20 pF input to output capacitance, the JHM series meets these requirements for designers of medical equipment.

The JHM series comprises a total of 20 models. The 3 W and 6 W units are available in +12 V d.c. or +24 V d.c. nominal input versions covering the ranges of +10 to +17 V d.c. or +20 to +30 V d.c. Single output models are available with +5, +12 or +15 V d.c. outputs. Dual output models offer ±12 or ±15 V d.c. options. Output voltages are fully regulated to within ±0,3% over all input conditions and less than ±2,0% over all load conditions.

The converters are capable of operating in most environments without any additional heatsinking or forced airflow. Full load output is available from -20°C to +60°C and up to the maximum case temperature of +100°C with derating. The units conform to EN55011 and EN55022 level A standards for conducted and radiated EMI without the need for any additional external components.
