FEATURES OF THE PTH FAMILY OF NON-ISOLATED WIDE OUTPUT ADJUST POWER

POLA™ COMPATIBILITY

SOFT-START POWER UP

PTH12010W, PTH12010L

SLTS205E–JUNE 2003–REVISED APRIL 2006

MODULES

The PTH/PTV family of nonisolated, 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

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

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

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

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

A) and PTH12030 (26 A) 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.

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

following sections.

The Auto-Track feature allows the power-up of multiple PTH 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
