2 Description

The UCC12050EVM-022 is intended to allow designers to evaluate the performance characteristics and abilities of the UCC12050DVE quickly and easily for use in isolated systems. The EVM allows users to test functions of the UCC12050DVE such as: Enable/Disable the device easily, Sync the device with an external clock source, detect potential external clock faults, select 5 V or 5.4 V output modes, and easily apply variable resistive loads to the output.

This EVM allows the user to easily measure efficiency across the input voltage range and varying output loads that the system might require. Section 5 documents how to make connections and measurements for testing efficiency across varying loads. Another feature of this EVM is the test points, which are labeled as TP1, TP2 and TP3, specially intended for use with oscilloscope probe ground springs, also known as pig tails, for measuring small signals such as input/output ripple voltages.
