TPS54386EVM Typical Performance Data and Characteristic Curves
Figure 5 through Figure 9 present typical performance curves for the TPS54386EVM. Since actual
performance data can be affected by measurement techniques and environmental variables, these curves
are presented for reference and may differ from actual field measurements.
