2.1 Configurations and Modifications

These evaluation modules provide access to the TPS548B23 features with jumpers for testing different configurations. All internal feedback configuration settings can be tested without board modifications, while for external feedback configuration, R6, R7, and the resistor divider network (R2 and R5) need to be installed. Modify the module if the desired performance is not achieved. Use the data sheet equations, WEBENCH, or an Excel design calculator to calculate external component values, verifying sufficient voltage and current ratings for all components.
