POLA Compatibility
The PTH/PTV family of nonisolated, wide-output adjustable power modules from Texas Instruments are
optimized for applications that require a flexible, high-performance module that is small in size. Each of these
products are POLA compatible. POLA-compatible products are produced by a number of manufacturers, and
offer customers advanced, nonisolated modules with the same footprint and form factor. POLA parts are also
ensured to be interoperable, thereby providing customers with true second-source availability.
Soft-Start Power Up
The Auto-Track feature allows the power up of multiple PTH/PTV modules to be directly controlled from the
Track pin. However, in a stand-alone configuration, or when the Auto-Track feature is not being used, the
Track
pin should be directly connected to the input voltage, V
I
(see
Figure 10
).
Figure 10. Power-Up Application Circuit
When the
Track
pin is connected to the input voltage, the Auto-Track function is permanently disengaged. This
allows the module to power up entirely under the control of its internal soft-start circuitry. When power up is
under soft-start control, the output voltage rises to the set-point at a quicker and more linear rate.
Figure 11. Power-Up Waveform
From the moment a valid input voltage is applied, the soft-start control introduces a short time delay (typically
