• Manufacturer: Astec Powe

1. Introduction
The PTH family of non-isolated, wide-output adjust power modules
from Artesyn Technologies are optimized for applications that require
a flexible, high performance module that is small in size. These
products are part of the “Point-of-Load Alliance” (POLA), which
ensures compatible footprint, interoperability and true second
sourcing for customer design flexibility. The POLA is a collaboration
between Artesyn Technologies, Astec Power and Texas Instruments
to offer customers advanced non-isolated modules that provide the
same functionality and form factor. Product series covered by the
alliance includes the PTHxx050W (6A), PTHxx060W (10A),
PTHxx010W (15/12A), PTHxx020W (22/18A), and the
PTHxx030W(30/26A).
From the basic, “Just Plug it In” functionality of the 6A modules, to
the 30A rated feature-rich PTHxx030W, series these products were
designed to be very flexible, yet simple to use. The features vary with
each product series. Table 1 provides a quick reference to the
available features by series and input bus voltage.

For simple point-of-use applications, the PTHxx050W series provides
operating features such as an ON/OFF inhibit, output voltage trim,
pre-bias start-up (3.3/5V input only), and overcurrent protection. The
PTHxx060W (10A), and PTHxx010W (15/12A) series add an output
voltage sense, and margin up/down controls. The higher output
current, PTHxx020W and PTHxx030W series also incorporates
overtemperature and shutdown protection. All of the products
referenced in Table 1 include Auto-Track™.
This is a feature unique to the PTH family, and was specifically
designed to simplify the task of sequencing the supply voltage in a
power system. These and other features are described in the
following sections.
