lists the R1 values for some common output voltages. For higher output voltages of 1.8 V or
above, a feedforward capacitor (C2) may be required to improve phase margin. Pads for this component
(C2) are provided on the printed-circuit board. Note that the values given in
(C2) are provided on the printed-circuit board. Note that the values given in
are standard values
and not the exact value calculated using

Test Setup and Results
This section describes how to properly connect, set up, and use the TPS54429EVM-608. The section also
includes test results typical for the evaluation modules and efficiency, output load regulation, output line
regulation, load transient response, output voltage ripple, input voltage ripple, start-up, and switching
frequency.
