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

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.
