Application Curves: TPS3840EVM

These application curves are taken with the TPS3840EVM using the TPS3840-Q1. Please see the TPS3840EVM User Guide for more information. The scope of the test below was to ensure that normal operation was maintained under typical cold crank and load dump conditions. This was verified by observing the input changing to its minimum and maximum value and the output remained both defined and accurate.
