Evaluation and Demonstration Boards and Kits are a group of products that enable engineers and other technically minded customers to quickly design applications for their products. These kits offer solutions to design needs and can greatly improve time to market for development projects. The UCC27423-4-5-Q1EVM is an example of such a product, and will be discussed in this article.

The UCC27423-4-5-Q1EVM is an evaluation module designed to provide a complete and low-cost design environment for the UCC27423 High Voltage Gate Driver, an IC designed for driving N-Channel MOSFETs and IGBTs. It evaluates the functionality and specifications of the UCC27423 in various applications such as dc-dc converter, motor driver, or driving load switches. It has the flexibility to configure the EVM using the B-EVAL-UCC27423-SM three-pin jumper to control path-through from output to input for flexibility while measuring input and output, the importance of which will be discussed later in the paper.

In order to understand the application field and working principle of the UCC27423-4-5-Q1EVM, it is necessary to understand the function of the UCC27423 High Voltage Gate Driver. The UCC27423 High Voltage Gate Driver is designed to drive N-Channel MOSFETs or IGBTs in low-side as well as high-side gate driver configurations. It is capable of generating high-speed switching waveforms while maintaining an output low enough to satisfy the requirements for low-side switching. The UCC27423 integrates a 600µs turn-on and a 260µs turn-off delay, thereby minimizing delays to the load while providing fast switching times. This makes it an ideal solution for applications such as motor drive, lighting, converter, and load switch applications.
