EVM User's Guide: UCC33421EVM-092
Evaluation Module for Automotive and Industrial
Applications
Description
The UCC33421EVM-092 is intended to allow
designers to evaluate the performance characteristics
and capabilities of the UCC33421-Q1 quickly and
easily for use in automotive and industrial bias
applications. The EVM allows users to test functions
of the UCC33421-Q1 such as: Enable/Fault (EN/FLT)
of the device as well as 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.
