6A/5A/3.5A DC-DCs for Medical Applications

February 18, 2019 by Scott McMahan

RECOM introduced medical-grade dc-dc modules which offer 3.5W, 5W, and 6W. These converters deliver all the critical features required for medical applications while keeping down the cost of these modular solutions. The REM3.5E, REM5E and REM6E series of medical-grade, regulated dc-dc converters feature reinforced 250Vac continuous working isolation with >8mm creepage/clearance providing 2 x MOPP. They qualify for medical B, BF, and CF applications due to their low 1µA leakage current.

The dc-dc converts come in a compact DIP24 package with standard pinout that has reinforced insulation of up to 10kVdc, which is sufficient for virtually every medical application. The tightly regulated single or dual outputs come with UVLO, SCP, OCP, and OVP.

The new dc-dc modules include REM3.5E, REM5E, and REM6E. The REM3.5E, 3.5W dc-dc module, has a Vin of 4.5Vin to 9Vin, 9Vin to 18Vin, 18Vin to 36Vin, and 36Vin to 75Vin depending on the model. It features a Vdc of 5Vdc, ±15Vdc, or 12Vdc. REM3.5E has an Iout of ± 117mA, ±145mA, ±194mA, ±350, 145mA, 233mA, 290mA, 388mA, and 700mA. It has an isolation of either 8kV or 10kV.

REM5E, a 5W dc-dc module, has the same Vin choices as the REM3.5E. It has a Vout of ±5Vdc, ±12Vdc, ±15Vdc, and 5Vdc, 9Vdc, 12Vdc, and 15Vdc depending on the variant. It has an Iout of ±166mA, ±208mA, ±277mA, ±500mA, 1.000A, 417mA, 556mA, 333mA, and 208mA. Like the other new dc-dc modules, the REM5E has isolation of 8kV or 10kV based on the variant.

REM6E is a 6A dc-dc module with the same choice of Vin as the other modules. I features a Vout of ±200mA, ±335mA, 667mA, 500mA, 400mA, and 250mA. Like the other two new modules, the REM6E has an isolation of 8kV or 10kV depending on the model.

The modules operate beyond 80% of efficiency in a wide temperature range from -40°C up to +85°C without derating. They are UL marked and certified to CB, IEC, EN and ANSI/AAMI 60601 3rd. Ed. Safety and 4th Ed. EMC medical standards. Samples and OEM pricing are available from authorized distributors or directly from RECOM.
