The world around us is changing rapidly. An autonomous aircraft controlled by smart devices stuffed with advanced electronic circuits is not a surprise anymore.
It is also quite normal that devices used by surgeons can keep the patient alive and often accompany them for the rest of their lives to assist their functioning or even make it possible at all. We can safely say that electronic devices are everywhere, and the automation trend as well as the trend for replacing mechanic solutions with the electronic ones are still accelerating.
The proper functioning of increasingly more advanced devices is based on using the highest quality components. The right power supply voltage and its quality are fundamental when it comes to electronic systems. Converters are used in order to transfer the current with the right parameters to the powered device. Considering the fact that a huge number of devices require direct current to operate, the high-quality DC/DC converters by Traco Powerare definitely worth attention.

How to choose the right converter
The DC/DC converter is a rather unassuming compact device whose main task is to stabilise the input voltage to adapt it to the level required by the device to which power is supplied. The ability to suppress interference makes it a crucial component of systems that require an exceptionally stable supply voltage. Due to its functions, the converter can be called as a kind of a protective component. One of the crucial functions of the product is reducing or increasing the value of supply voltage. The following configurations of the converters are available:
- Step-up –the output voltage transferred to the powered device after the conversion is higher than the voltage supplied to the converter;
- Step-down – the output voltage transferred to the powered device after conversion is lower than the supply reaching the converter;
- Step-up/step-down – the converter is adapted to transfer the current whose voltage may be both higher and lower than the input voltage.
The term “protective component” refers to the fact that certain models of the DC/DC converters offer galvanic isolation (preventing the current from transferring between adjacent function blocks) that adjusts the value of output voltage with no interference. It operates by way of switching the voltage alternately on and off at an exceptionally high rate. Apart from that, they offer protection against surges and short-circuits as well as overheating and overloading, which is why both the powered device and the converter are protected from the unwanted consequences of the abovementioned occurrences.
It is easy to guess that due to their exceptionally important function and a series of capabilities connected with using the DC/DC converters, it is crucial to choose the right model for the specific application.
Traco Power – wide range of converters and reliable quality
For many years, Traco Power has been specialising in all types of DC/DC converters for customers from all over the world. Due to the high quality of products and the enormous success achieved in the 1970s, the company expanded to all the continents, gaining the clients’ recognition. To meet the requirements of the customers, Traco Power is constantly developing their portfolio, introducing a series of innovations which stimulates growth in relation to the voltage conversion technology and improved safety of use.
The fundamental parameters of DC/DC converters by Traco Power in the TME catalogue:
- Switching frequency – 90 – 500kHz range;
- Power rating – from 1 to 60W;
- Input voltage – from 4.5 to 160V;
- Output voltage – from 3.3 to 48V DC;
- Output current – from 35mA up to 12.2A.
One of the DC/DC step-down converters is the TDN 1-1210WI TRACO POWER model. It is a compact converter with dimensions of 13.2x9.1x10.2mm, adapted to operate in the temperatures of -40÷90°C. Products from the TDN series are fully adjustable, highly efficient direct current converters. The devices are designed to operate in a wide voltage range and do not require a minimum load. The manufacturer declares that they are developed in compliance with the IEC/EN 62368-1 standard, confirmed by 1500V DC voltage tests (60 sec.).
The device converts input voltage of 4.5-18V to a stable voltage of 3.3V DC with a switching frequency of 100kHz and efficiency of 77%. The power rating of this converter is 1W, and the output current of the device reaches the value of 300mA. The converter features short-circuit protection.
Another example is a step-up converter, the DC/DC TEN 60-2418WIR TRACO POWER model. The two presented products vary not only when it comes to the enclosure type and size (50.8x40.7x25.4mm) but in particular in the technical data. This converter has the power rating of 60W, input voltage of 18-36V and output voltage of 48V DC. The output current is 1250mA, and the switching frequency is 250Hz. The high operating efficiency (92%) is also noteworthy. The device is equipped with a voltage drop protection. It is used in railway and transport systems. The quality of the converter is confirmed by a range of certificates i.e. certifying compliance with the EN 50155 and EN 61373 standards, material requirements regarding hazards caused by the presence of fire – EN 45545-2 as well as the safety approval compliant with IEC/EN 62368-1 and UL62369-1.
The two abovementioned examples are enough to see that Traco Power offers products adapted to operate with demanding devices with a very wide range of parameters. The offered devices are properly certified, which confirms their quality and safety.
