DC DC Converters

DC-DC Power Converters are electronic devices that convert electrical energy from one voltage level to another. The most basic examples are those used in computers and telecommunication systems which convert 12V DC into various levels for internal loads. Generally speaking, there are two types of DC-DC converters: isolated and non-isolated.

An isolated converter uses a transformer to transfer power between two separate input and output circuits. This type of converter is useful when the input and output circuits are electrically isolated from each other. Non-isolated converters, on the other hand, use capacitors and inductors to transfer power between the input and output circuits without the need for an intermediary transformer. These types of converters are usually used in electronic equipment and circuits which require a specific voltage range or polarity.

The STMGFW154815-JN1 is a non-isolated, Multi-Mode DC-DC Converter designed for high voltage applications. The STMGFW154815-JN1 is capable of operating from a wide input voltage range up to 48V and delivering up to a 15A output current. The device is suitable for a variety of industrial control and electrical power conversion applications such as solar inverters, battery chargers, machine control systems, and portable power supplies. It offers robust protection features to ensure reliable operation under extreme conditions.

The STMGFW154815-JN1 is based on a buck-boost converter topology and utilizes an advanced control loop to provide superior efficiency and performance.
