DC-DC converters provide the efficient and effective means of converting one form of DC (direct current) power to another. This is an essential technology for now-a-days’ power electronic applications, be it in consumer electronics, industrial or automotive applications, or even in renewable energy and battery charging applications. VI-J3T-EY-F1 is one such DC-DC converter technology. It is a regulated isolated constant-voltage and constant-current switching DC-DC converter that exhibits high efficiency, excellent power density, wide input voltage and output voltage range, as well as the capability of working with high output power loads.

VI-J3T-EY-F1 works on the principles of flyback switching converter whose working is based on the simple concept of energy transfer. The VI-J3T-EY-F1 adopts buck-boost topology with a quasi-resonant flyback structure. In this quasi-resonant flyback structure, energy is stored in the transformer during the time when switch is on, and then is delivered to the load when switch is off. A control circuit is used to adjust the duration of the on and off times to ensure the regulation requirements of the output.

The output is isolated and regulated with a voltage clamp circuitry. This eliminates the need for an optocoupler, allowing the application workload to be reduced. The VI-J3T-EY-F1 utilizes a soft-switching technology that minimizes switching losses and EMI noise, resulting in high conversion efficiency. The converter also possesses a wide input voltage range which helps in avoiding the problems caused by input voltage variation, and provides an output voltage range of up to 60V. The VI-J3T-EY-F1 also has the capability to work with higher power loads while providing a constant-voltage and constant-current output.

The VI-J3T-EY-F1 is suitable to use in a variety of DC-DC applications, such as for mobile, telecommunication, medical, generic switched mode power, industrial, domestic appliances, automotive, and high-voltage battery charging. Being a constant-voltage and constant-current switching DC-DC converter, it can be employed in applications that require operating with a fixed output voltage under varying load, allowing for a wide frequency range and low output noise.

To meet the demands of these various applications, the VI-J3T-EY-F1 adopts a 6-pin package and contains all the functions to meet the needs of the system. The VI-J3T-EY-F1 also features protection functions like short circuit, over-current and over-voltage protection, as well as soft start, thereby providing a safe operation and further peace of mind for the user.

In summary, the VI-J3T-EY-F1 is highly efficient DC-DC converter technology that has a wide input voltage range and can work with higher power loads. It can be employed in applications that need operated with a fixed output voltage under varying load. The 6-pin package provides all necessary functions and also features with protection functions like short circuit, over-current and over-voltage protection, as well as soft start. Therefore, it is suitable to use in a variety of DC-DC applications.
