The STEVAL-PCC008V1 evaluation board has been designed to explore the following typical applications:

1. Power supply for computer and consumer electronics.
2. Power supply for industrial, automotive and telecom applications.
3. High current or multi-channel power conversion.

In addition, this evaluation board offers some additional applications:

• DC/DC conversion.
• Low voltage isolated power conversion.
• High power density.

Working principle of STEVAL-PCC008V1

The operation of the STEVAL-PCC008V1 evaluation board is based on a single-ended primary inductor-based (SEPIC) isolated forward converter topology with the SPP04N60C3 N-channel MOSFET being used as the main switching element. It has a two-stage power converter structure; its input stage is a buck converter for bulk voltage leveling and the output stage is a forward converter for voltage and current regulation.

The main operations of the board are as follows:

1. The input stage is a buck converter, with the voltage on the bulk capacitor set by the feedback loop. When the SPP04N60C3 MOSFET is turned on, it draws current from the input to charge the bulk capacitor and provide power to the load. This process is then repeated.
2. The output stage is a forward converter, with the output voltage set by the feedback loop. When the SPP04N60C3 MOSFET is turned off, it stops drawing current from the input and allows the current to flow through the primary winding of the transformer. This allows power to be transferred from the input to the output and regulates the output voltage.

Conclusion

The STEVAL-PCC008V1 evaluation board is an excellent tool for evaluating the performance of the SPP04N60C3 N-channel MOSFET in an isolated forward converter topology. It offers a wide range of applications, such as power supply for computer and consumer electronics, industrial, automotive and telecom applications, and high current or multi-channel power conversion. Moreover, the board features two jumpers and one toggle switch for easy configuration. The board operates on the basis of a single-ended primary inductor-based (SEPIC) isolated forward converter topology, with the input stage being a buck converter and the output stage being a forward converter.
