EVM User's Guide: UCC33420Q1-EVM
UCC33420EVM-080 Evaluation Module for Automotive and
Industrial Applications
Description
The UCC33420EVM-080 is intended to allow
designers to evaluate the performance characteristics
and capabilities of the UCC33420-Q1 quickly and
easily for use in automotive and industrial bias
applications. The EVM allows users to easily probe
during test and to test functions of the UCC33420-Q1
such as, Enable/Fault (EN/FLT) of the device and
configure the isolated output voltage for VISO = 5.0V
or VISO = 5.5V using the SEL pin and apply variable
loads to the outputs. The EVM allows the user to
measure efficiency across the input voltage range and
vary output loads according to system requirements.

1 Evaluation Module Overview 1.1 Introduction This user’s guide provides a description as well as directions for use of the UCC33420EVM-080 to evaluate the UCC33420-Q1. The UCC33420-Q1 is a high efficiency, low-emissions, 3 kV isolated DC-DC converter capable of delivering 1.5 W of power in an integrated VSON-12 package. The UCC33420-Q1 delivers class- leading efficiency in power conversion from the primary to the secondary side while removing the need for external transformers or power modules commonly used in existing designs. - Page 3 0402, and 22-µF ceramic bypass capacitors close to VCC and GNDS pins.
