1 Introduction
The UCC27423-4-5-Q1 EVM is a high-speed dual MOSFET evaluation module that provides a test
platform for a quick and easy startup of the UCC2742x-Q1 driver. The EVM is powered by a single 4 V to
15 V external supply and features a comprehensive set of test points and jumpers. All of the devices have
separate input and output lines and all devices share a common ground. Enable (ENBL) functions are
provided to allow better control of the operation of the driver applications, driver signals of the devices can
be enabled or disabled through the same enable pin.
1.1 Related Documentation
For more information on the UCC27423-Q1, UCC27424-Q1, and UCC27425-Q1 devices refer to
UCC2742x-Q1 Dual 4-A High-Speed Low-Side MOSFET Drivers With Enable.
1.2 UCC2742x-Q1 Applications
The UCC2742x-Q1 family of devices can be used in the following applications:
• Switch Mode Power Supplies
• DC-DC Converters
• Motor Controllers
• Class D Switching Amplifiers

3 EVM Test Points, Jumpers, and Connectors
This section describes the test points, jumpers, and connectors on the EVM as well as how to connect, set
up, and properly use the EVM. Each device has independent signal connections, but all devices have a
common VCC and ground.
3.1 EVM Test Points
Table 2 lists the test points and functional descriptions. All pins of the device are broken out to test points
on the EVM.
