Supply input — Nominal operating range is 6V to 36V . A small amount of internal capacitance is contained within
the package assembly. Additional external input capacitance is required between this pin and exposed pad (PGND).
synchronize the PWM operating frequency to an external frequency source. When not using synchronization connect
to ground. The module free running PWM frequency is 812 kHz (Typ).
Enable — Input to the precision enable comparator. Rising threshold is 1.279V typical. Once the module is enabled,
a 21 uA source current is internally activated to facilitate programmable hysteresis.
Soft-Start/Track — To extend the 1.6 mSec internal soft-start connect an external soft start capacitor. For tracking
connect to an external resistive divider connected to a higher priority supply rail. See applications section.
Feedback — Internally connected to the regulation, over-voltage, and short-circuit comparators. The regulation
reference point is 0.796V at this input pin. Connect the feedback resistor divider between the output and AGND to
set the output voltage.
