1.3 Modifications

These evaluation modules are designed to provide access to the features of the TPS54A24. Some modifications can be made to this module. When modifications are made to the components on the EVM, the compensation components connected to the COMP pin may need to be changed. Changes to the fSW, output voltage, output inductor, and output capacitors may require a change in the external compensation. Ensure all components have sufficient voltage and current ratings. Table 1-3 gives some example values for different applications.
