DC-DCs for Medical Applications with <2μA Leakage

Traco Power now offers the TIM 2 and TIM 3.5 Series of 2- and 3.5-Watt dc-dc converters for medical applications. They provide a reinforced isolation of 5000Vac(rms) and come in a compact DIP-16 or SMD-16 package.

With a low leakage current of less than 2µA the converters are predestined to insulate electrical equipment from the applied parts to patient (BF classification). The models are approved to IEC/EN/ES 60601-1 3rd edition for 2xMOPP up to an altitude of 5000m and come along with an ISO 14971 risk management file.

They comply with latest EMC requirements IEC 60601-1-2 4th edition for medical equipment. A high efficiency enables an operation at environment temperature of -40 up to 95°C (90°C for TIM 3.5).

Models are available with outputs voltages of 3.3-, 5.0-, 9.0-, 12-, 15-, 24-, ±12- or ±15-Vdc. Available input voltage ranges are 4.5- to 12-Vdc, 9.0- to 18-Vdc, 18- to 36-Vdc, and 36- to 75-Vdc.

Summary of features:

  • 2 Watt and 3.5 Watt in compact DIP or SMD package
  • Leakage current <2 µA for BF-applications
  • Extended operating temperature range -40 to +95°C
  • Latest medical safety approvals and EMC compliance
