Notes on Use of Auto-Track
1. The Auto-Track function tracks almost any voltage ramp during power up, and is compatible with ramp
speeds of up to 1 V/ms.
2. The
Track
pin voltage must be allowed to rise above the module set-point voltage before the module
regulates at its adjusted set-point voltage.
3. The absolute maximum voltage that may be applied to the
Track
pin is the input voltage V
I
.
4. The module cannot follow a voltage at its track control input until it has completed its soft-start initialization.
This takes about 20 ms from the time that a valid voltage has been applied to its input. During this period, it
is recommended that the
Track
pin be held at ground potential.
5. The Auto-Track function is disabled by connecting the
Track
pin to the input voltage (V
I
). When Auto-Track is
disabled, the output voltage rises at a quicker and more linear rate after input power has been applied.
