7 Measurements

Test data can be found in the Application Curves section of the following data sheets:

Additional bench test data for efficiency in specific conditions for this power tree can be seen in this section. TI PMIC Efficiency Estimation Tool (PEET) can be used also for calculating efficiency and thermal performance: PEET-GUI.

Measurements were taken on the LP87320Q1EVM with default components.
