FEATURE DESCRIPTIONS (CON.)
The output voltage tracking feature (Figure 27 to Figure

connections. If the tracking feature is not used, the
TRACK pin of the module can be left unconnected or tied
to Vin.

For proper voltage tracking, input voltage of the tracking
power module must be applied in advance, and the
remote on/off pin has to be in turn-on status. (Negative
logic: Tied to GND or unconnected. Positive logic: Tied to
Vin or unconnected)
