The PTH/PTV family of non-isolated, 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, non-isolated modules with the same footprint and form factor. POLA parts are also

assured to be interoperable, thereby providing customers with true 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.
