The PTH/PTV family of non-isolated, wide-output adjustable power modules 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 second-source availability.

From the basic, Just Plug it In functionality of the 6-A modules, to the 30-A rated feature-rich PTHxx030, these

products were designed to be very flexible, yet simple to use. The features vary with each product. Table 5

provides a quick reference to the features by product series and input bus voltage.

For simple point-of-use applications, the PTH12050 (6A) provides operating features such as an on/off inhibit,

output voltage trim, prebias start-up and overcurrent protection. The PTH12060 (10A), and PTH12010 (12A)

include an output voltage sense, and margin up/down controls. Then the higher output current, PTH12020 (18A)

and PTH12030 (26A) products incorporate overtemperature shutdown protection.

The PTV12010 and PTV12020 are similar parts offered in a vertical, single in-line pin (SIP) profile, at slightly

lower current ratings.

All of the products referenced in Table 5 include Auto-Track™. This feature was specifically designed to simplify

the task of sequencing the supply voltages in a power system. This and other features are described in the

following sections.
