Evaluation and Demonstration Boards and Kits

The UCC21220EVM-009 is an evaluation and demonstration board and kit designed for measuring the performance of the UCC21220 multi-phase controller. This evaluation board is a great way to evaluate whether the controller is suitable for a specific application. It provides a convenient and cost-effective way to demonstrate and evaluate the capabilities of the UCC21220 multi-phase controller. The board is also capable of generating both current-mode and voltage-mode pulse-width modulated control signals for driving a multi-phase DC power converter.

Application Field

The UCC21220EVM-009 is a multiphase controller evaluation board and kit designed to use in a variety of applications. It is the perfect tool to evaluate the UCC21220 controllers for relatively low-power, high-speed applications such as laptop power supplies, industrial motor drives, home appliance motor drives, and PFC (power factor correction) generators.

Working Principle

The UCC21220EVM-009 can be used to quickly evaluate how the UCC21220 controller works in a particular application. The primary principle of operation is to use a current-mode control algorithm to regulate the output voltage and current, creating a highly efficient and highly predictable converter. It also has over-current protection, which ensures reliable operation each and every time.

The UCC21220EVM-009 controller operates in two types of control modes: voltage-mode and current-mode. In voltage-mode control, the active switch duty cycles are adjusted to maintain the output voltage of the power converter at the desired level. In current-mode control, the active switch duty cycles are adjusted to maintain the output current of the power converter at the desired level regardless of the output voltage. This ensures not only voltage regulation but also superior current regulation.

Conclusion

The UCC21220EVM-009 board and kit provides engineers with an easy way to evaluate the performance of the UCC21220 multi-phase controller. It is a great way to experiment and demonstrate the capabilities of the UCC21220 multi-phase controller in various applications such as laptop power supplies, industrial motor drives, home appliance motor drives, and PFC generators. Moreover, it is capable of generating both current-mode and voltage-mode pulse-width modulated control signals for driving a multi-phase DC power converter.
