Board-Mounted DC DC Converter 12v to 5v in the Medical Applications

Posted by HV mtech on December 12th, 2019

Home and professional healthcare is a quickly expanding market. More and more, electronic monitoring can be used for everything from critical-care vital sign monitoring to ordinary bed occupancy sensors. The power for electronics usually requires safety galvanic isolations. This article describes why you need power isolation in normal situations as well as defines the security standards, which require application. For instance, a board-mounted DC DC converter 12v to 5v might be a fit, depending on the required specifications.

The Requirements for Isolation in High Voltage Switching Power Supply is Clear

It’s obvious why a DC DC converter 12v to 5v is used in the medical applications that require high voltage switching power supply protection against electric shock.In the case the power supply stops working, you may have a lethal and direct connection from the high voltage switching power supplyto the conductors in close contact with the patient, perhaps even to the internal organs for aggressive sensors. The inverse is also true as the medical equipment needs to provide protection against grounding in the “floating” patient, which is subjected to the external high voltage switching power supply. For instance, this could be true during defibrillation or cauterization procedures.

DC DC converter 12v to 5vMay Need Isolation

In medical equipment, there is often a requirement for the DC DC converter 12v to 5v that may take the battery-or-AC-derived DC inputs and convert the voltage levels into practical values requiredfora circuit or powering the equipment peripherals, as is the case with sensors. In most cases, the DC/DC input has a low voltage, like 12v to 5v, with low-voltage outputs like +/-5V or 3.3V. Working isolation is not required; however, it might be used to break the ground loops to help control cross-talks between the sensors in orderto decreasethe electromagnetic interference or produce negative rail voltages from the positive supplies. Where the isolation is not required functionally, it might be required for security reasons, although input or output voltages are lower and well inside the limit of “safe” voltage.

DC DC Converter 12v to 5vMay CreatePart of theOverall Medically Approved Systems

The additional level might be the DC DC Converter 12v to 5v between the AC/DC outputs and areas of the electrical system, which are available to patients or operators. The general cost might be much less when compared to buyingcertified and committed medical supply.However, there are also some specifications for the leakage current for medical environments that the IT-rated supply can almost exceed which needs to be considered.
