A DC-DC converter is a device that converts direct current (DC) from one voltage level to another. It is used to adjust the voltage level of a power source to match the voltage level required by a load. DC-DC converters are commonly used in a wide range of applications, including in automobiles, portable electronics, and renewable energy systems. They can also be used to isolate or galvanically separate different sections of an electrical system.
It depends on the specific DC-DC converter you are using. Some dual-output DC-DC converters are designed to be used with both outputs connected and active at all times, while others are designed to allow one of the outputs to be used independently of the other.
For example, if a dual-output DC-DC converter is designed as a “tracking” converter, it will have both outputs connected and active at all times, and the outputs will be closely regulated to track each other. In this case, it’s not recommended to use only one output.
On the other hand, if a dual-output DC-DC converter is designed as a “split” converter, it’s typically possible to use only one output independently of the other, with the other output left open or connected to a suitable load.
It’s important to check the datasheet of the specific DC-DC converter you are using for more information on how it is designed and how it can be used. It’s also recommended to check the load requirements and voltage levels of the device you want to use it with, and make sure that the DC-DC converter you’re using can supply the appropriate voltage and current for the load.
There are several types of DC-DC converters that can be designed to minimize or reduce noise emissions, including:
It’s worth noting that in addition to the type of DC-DC converter, the design and layout of the converter circuit, the quality of the components used, and the operating environment can all have an impact on the amount of noise that a converter generates.
There are many manufacturers of DC-DC converters, and the best one for a particular application will depend on a variety of factors such as the specific requirements of the application, the operating environment, and the price point. Some well-known manufacturers of DC-DC converters include:
It’s worth noting that these companies offer a variety of options for different power needs and industries. Some of them are specialized in higher power options and some in more compact or low power options. It’s also recommended to check their certifications and quality standards that they comply with, to ensure they meet specific safety, performance and environmental requirements.
