The slow start time is typically 3.6 ms, and is controlled internally. The slow
start time cannot be made faster than 3.6 ms.
The TPS54x72EVM–222 EVM also supports alternate output filter configura-
tions by means of pads located on the back side of the PCB. The positions for
C15, C16, and C17 provide space for up to three electrolytic type surface
mount capacitors, while the position for L2 accommodates popular inductors
such as Vishay IHLP-5050 series with a 0.5 in.

0.5 in. package. Since
changes in the output filter affect the overall loop response, the user may find
it desirable to change the values used in the compensation network (R1, R2,
R3, C1, C2, and C3). The 0-
resistor R8 in the feedback path is provided as
a convenient place to break the loop for testing any compensation value
changes. While the provided compensation network can provide a stable out-
put for a wide variety of output filter component values, it is always a good idea
to verify any changes to the output filter or compensation network.
