DC-DC converters are essential components used in various applications to convert a direct current (DC) voltage from one level to another. They play a critical role in ensuring efficient power management across different electronic devices and systems. DC-to-DC voltage converters come in isolated and non-isolated varieties, each serving specific purposes depending on the application's safety and efficiency requirements.

Isolated DC-DC converters convert a source of direct current (DC) from one voltage to another and contain an electrical barrier between the input and output to improve safety.

Non-isolated DC-DC converters, on the other hand, do not have an electrical separation between input and output. They are typically used in low-power applications where efficiency and compact size are critical.

Whether you need a 12V-to-12V DC-DC converter, a DC-to-DC regulator, or a DC-to-DC converter module, RS NZ has the right solution for your needs.

## **What are They Used For?**

Isolated DC-DC converters are used within equipment and devices containing different circuits or sub-circuits where it is necessary to convert the voltage of a DC supply from one level to another. An example would be a device with various circuits, some needing 12 volts (V) and others needing 5V. An isolated 12v DC-DC converter could be used to buck the 12V input to a stable 5V for the lower voltage circuits.

On the other hand, non-isolated DC-DC converters are suitable when isolation between the input and output circuits isn't critical. They are often more compact and cost-effective due to the lack of isolation components. For converting AC to DC, an [AC-DC converter](https://nz.rs-online.com/web/c/semiconductors/power-management-ics/ac-dc-converters/) would be used.

## **Types of Isolated DC-DC Voltage Converters**

Isolated DC-DC converters come in a wide range of input and output voltages in both single outputs and dual outputs. At RS NZ, we also offer medical, railway and [site-approved converters for safety-critical applications](https://nz.rs-online.com/web/content/discovery/ideas-and-advice/workplace-on-site-safety-guide).

### **Single Output Converters**

Single-output DC converters are ideal for applications requiring a single, regulated voltage level. They provide a clean and stable power source for various electronic circuits.

### **Dual Output Converters**

Dual output isolated DC-DC converters offer the versatility of generating two independent, regulated voltage levels from a single input source. This eliminates the need for multiple converters, simplifying your design and saving space.

### **Medical Approved Converters**

For applications in the medical field, safety is paramount. Our medical-grade isolated DC-DC converters comply with rigorous medical safety standards, ensuring reliable and dependable power delivery for critical medical equipment.

### **Railway Approved Converters**

The railway industry has specific requirements for power electronics. Our railway-approved DC-DC isolators meet stringent railway standards for shock, vibration, and temperature extremes, ensuring reliable operation in harsh railway environments.

### **High Power Density Converters**

For applications requiring high power output in a compact space, high-power density DC-DC converters with isolation are the perfect solution. They deliver superior efficiency and minimise footprint, ideal for space-constrained environments.

### **Low Power Converters**

Low power isolated DC-DC converters are perfect for applications where minimising power consumption and size is critical. They offer efficient power conversion for low-power devices while maintaining isolation benefits.

## **Package or Module Types**

Isolated DC-DC converters and non-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
