Essential Characteristics of DC-to-DC Converters

When choosing DC-to-DC converters for a device, engineers pay attention to different characteristics and parameters, with the most important ones being the following:

Input voltage

This parameter is defined by the power source used. Different power sources (for instance, AC-to-DC adapters or batteries) provide different input voltages. When designing electronics, a hardware development company must make sure the DC-DC converter can withstand these voltages.

Output voltage

DC-DC converters can produce either fixed or adjustable output voltage. The latter can vary from a minimum to a maximum value. In both cases, the choice of models is defined by the voltage range required by the load.

Output current

Output current (along with the output voltage) defines the electrical power that a converter can provide.

Efficiency

Efficiency is the percentage of the input power delivered to the output. It can be calculated with the following formula:

DC-to-DC efficiency formula.

As mentioned above, the efficiency of 24-v-to-230-v-converters can vary a lot. In some cases, this parameter is considered crucial. For example, if the device is powered by batteries, the efficiency defines how long the device can work before you have to replace them.

In some cases, efficiency itself is not as important. However, the energy lost during conversion dissipates as heat. This in turn can lead to undesirable consequences.

Temperature

Since extra energy goes into heat, overheating can become a serious issue. This problem can be partially solved with proper casing. But in certain cases, one may have to use additional thermal protection.

Size and mounting types

DC-DC converters are available in many package types. If it needs to be mounted into a PCB, designers can choose from a variety of mounting styles, including surface or through-hole mounting, single in-line or dual in-line pin. The size also matters when engineers develop small devices.

Stable supply

And finally, when picking converters for a device, it’s also important to make sure the manufacturer will not stop supporting the model in the near future. That’s why our team always gives priority to the latest models.

Common Issues Related to DC-DC Converters

Another common problem for any electronics design company is meeting various regulatory and certification requirements. Using DC-DC converters can affect the device’s characteristics and features from the safety and electromagnetic compatibility perspectives. Furthermore, different applications can impose additional requirements.

For example, replacing a switching converter with a cheaper linear one may require a cooling system. But such a system may turn out to be even more expensive.
