Track
This is an analog control input
that enables the output
voltage to follow an external
voltage. This pin becomes
active typically 25 ms after
the input voltage has been
applied, and allows direct
control of the output voltage
from 0 V up to the nominal
set-point voltage. Within this
range the module’s output
voltage follows the voltage at
the Track pin on a volt-for-volt
basis. When the control
voltage is raised above this
range, the module regulates
at its set-point voltage. The
features allows the output
voltage to rise simultaneously
with other modules powered
from the same input bus. If
unused, this input should be
connected to VI .
NOTE: Due to the
undervoltage lockout feature,
the output of the module
cannot follow its own input
voltage during power up. For
more information, see the
related application note.
21
Inhibit and UVLO The Inhibit pin is an open-
collector/drain, negative logic
input that is referenced to
GND. Applying a low level
ground signal to this input
disables the module’s output
and turns off the output
voltage. When the Inhibit
control is active, the input
current drawn by the
regulator is significantly
reduced. If the Inhibit pin is
left open-circuit, the module
produces an output whenever
a valid input source is
applied.
This pin is also used for input
undervoltage lockout(UVLO)
programming. Connecting a
resistor from this pin to GND
(pin 13) allows the ON
threshold of the UVLO to be
adjusted higher than the
default value. For more
information, see related
application information.
22
SmartSync
This input pin sychronizes the
switching frequency of the
module to an external clock
frequency. The SmartSync
feature can be used to
sychronize the switching
frequency of multiple
modules, aiding EMI noise
suppression efforts. The
external synchronization
frequency must be present
before a valid input voltage is
present, or before the release
of inhibit control. If unused,
this pin MUST be connected
to GND. For more
information, please see the
related application note.
