DC DC Converters

The DC DC Converters are electrical components that are used to convert between two different DC voltage levels. Among the most common types of DC DC converters are switched mode power supplies, chopper and step-down transformers. Here we will discuss one such example, the DFC25E48T5/12.

DFC25E48T5/12 Application Field and Working Principle

The DFC25E48T5/12 is a SMPS (switched mode power supplies) type DC DC converter designed for use in consumer, industrial, medical and military applications. It has a nominal input voltage of 48V DC and can output voltage of up to 25V DC. The maximum output current is 5A and power is 2.5W. It is also very efficient, with an average full-load efficiency of up to 92%.

The working principle of this converter is based on a buck topology. This means that the input voltage is applied across an inductor and this creates a magnetic field. A switch (transistor) is then controlled by an internal oscillator, which is also fed from the input voltage. The transistor is used to connect and disconnect the inductor from the output voltage.

When the switch is open, the output voltage is at a low level (1V). When the switch is closed, the current in the inductor increases, creating a higher magnetic field. The resulting voltage across the inductor is then “buckled” and the output voltage rises. This bucking principle is used by the converter to regulate the output voltage, as the switch is further controlled by the internal oscillator.

The switching frequency of the oscillator varies depending on the input voltage and output current. This means the DFC25E48T5/12 is capable of automatically adapting its switching frequency for same output voltage level at different input voltage levels. This allows for great flexibility in applications.

The converter also features protection against overload and short-circuit conditions. It includes a thermal shutdown feature, which automatically shuts off the converter if the temperature of the internal circuit exceeds a certain level. This helps to protect against damage from overloads, resulting in longer lifespan and enhanced safety.

The small size, high efficiency, wide input range, wide output voltage range, and low standby current make the DFC25E48T5/12 an attractive choice for DC DC conversion applications. Its ability to automatically adjust its switching frequency, as well as its protection features, make it a perfect solution for the most demanding applications.
