Isolated DC-DC converters convert a source of direct current (DC) from one voltage to another while ensuring an electrical barrier between the input and output to improve safety. Also known as DC voltage converters, these devices are integral to a wide range of applications across various industries, including telecommunication equipment, industrial equipment, and consumer electronics.

The operating principle of these DC-to-DC transformers involves switching regulators that efficiently change an input DC voltage to a different output DC voltage, providing precise voltage control and isolation to protect the devices.

## **What Are DC-to-DC Converters Used for?**

Isolated DC-DC converters are used within equipment and devices containing different circuits or sub-circuits requiring distinct voltage levels. They are employed to convert the voltage of a DC power supply from one level to another effectively, such as converting a 12v to a 48v DC-to-DC converter for specific power requirements. When converting AC to DC, for instance, an [AC-DC converter](https://au.rs-online.com/web/c/semiconductors/power-management-ics/ac-dc-converters/) would be used.

Typical industrial applications include powering remote sensors and telecommunications equipment where signal integrity is paramount, as well as providing isolated power sources for sensitive electronic devices to enhance operational safety and reliability.

## **Types of DC-to-DC Converters**

DC-to-DC inverters come in a wide range of configurations to meet diverse application needs. They come with a range of input and output voltages and can be found in single or dual-output versions. Specific types also meet stringent safety standards, including medical and railway-approved converters, which are crucial for safety-critical applications. Key specifications include:

- Input voltage ranges, typically from as low as 2V up to 400V.
- Output voltage adjustments to match device requirements.
- Operating temperature ranges ensure performance under extreme conditions.
- Switching frequency to optimise efficiency.
- High isolation voltage and isolation resistance for enhanced safety, particularly for high-voltage DC-to-DC converters.
- Overvoltage protection to prevent damage to the circuit.
- IP ratings to indicate the degree of protection against solid objects and liquids.

### **Package or Module Types**

Isolated DC-DC converters come in many shapes and packages to suit every eventuality. Some of the most popular are:

- DIP16
- DIP24
- PDIP
- SIP
- Encapsulated
- Full and half brick

### **Mounting Types**

DC-to-DC converters are used in many different environments and applications, so they need to be easy to mount or install. Our products come in a range of mounting options, including:

- Chassis mount
- DIN-Rail mount
- Flange mount
- PCB mount
- Rackmount
- Surface mount
- Through-hole

## **The Advantages of Isolated DC-to-DC Converters**

Isolated DC-DC converters provide critical advantages in electronic systems, including enhanced safety through electrical isolation, which prevents noise and interference from affecting device performance. Their ability to precisely control output voltage ensures the longevity and reliability of sensitive electronic components.

## **Isolated vs Non-Isolated DC-to-DC Converters**

The key difference between isolated and non-isolated DC-to-DC converters lies in the electrical isolation between the input and output. Isolated converters prevent direct electrical paths, enhancing safety and noise reduction, crucial in sensitive and critical applications. Non-isolated converters, while simpler and more cost-effective, do not provide this level of protection.

## **Industrial Applications of DC-to-DC Converters**

DC-to-DC converters are indispensable in industries like automotive, where they manage power supply within vehicles, aerospace for equipment safety, and healthcare for reliable medical devices operation. Each application benefits from the specific attributes of these converters, ensuring efficient and safe operation of critical systems.
