APPLICATIONS INFORMATION
External Reference Input (DDR Mode)
If SRLIM is tied to SVIN, the TRACK/SS pin can be used
as an external reference input between 0.3V and 0.5V, if
desired (see Figure 13).
In DDR mode, the maximum slew rate is selected. If
VTRACK/SS is within 0.3V and 0.5V, the PGOOD function
is enabled. If VTRACK/SS is less than 0.3V, the output cur-
rent foldback is disabled and the PGOOD pin is always
pulled down.
