POLA-compatible, non-isolated modules offer innovative multi-phase switching

Texas Instruments Incorporated announces the industry's first 50-A and 60-A POLA-compatible, non-isolated, plug-in power modules with an innovative multi-phase switching topology. Achieving power conversion efficiency up to 96 percent, the small, ready-to-use modules are capable of powering today's most densely populated power systems found in advanced computing platforms and servers.

The new 50-A PTH12040 and 60-A PTH04040 plug-in power modules extend TI's widely adopted PTHxx family of non-isolated modules that combine a wide range of input voltages and feature Auto-Track sequencing. The unique Auto-Track feature allows the outputs of multiple modules to track one another or a common voltage during power-up and power-down transitions.

The PTH12040 operates from input voltages from 8 V to 14 V, and can supply an output current of up to 50-A with output voltages of 0.8 V to 5.5 V, making it ideal for systems that use a loosely regulated 12-V intermediate distribution bus. The PTH04040 supports input voltages from 2.95 V to 5.5 V, and can be set to any output voltage in the 0.8 V to 3.6 V range. The 60-A module efficiently powers advanced computing systems that use either a 3.3-V or 5-V distribution bus.

In addition to TI's Auto-Track sequencing technology, both modules incorporate several advanced features, including an on/off inhibit and margin up/down controls. A differential remote output voltage sense ensures tight load regulation, and an output over-current and over-temperature shutdown feature protects against most load faults. In addition, the PTH04040 and PTH12040 include a programmable under-voltage lockout function that allows the turn-on threshold to be customized.

Introduced in 2003, the PTH family of non-isolated plug-in modules is fully POLA-compatible. Members of the POLA Alliance offer customers advanced, non-isolated modules with the same footprint and form factor. POLA devices are fully interoperable, providing customers with true second-source availability.

The PTH12040 and PTH04040 modules are available in volume today from TI and the company's authorized distributors. Available in through-hole and low-profile, double-sided surface-mount packages, suggested pricing for the PTH12040 is $35.00 per 1,000 units, and $35.00 for the PTH04040 per 1,000 units. Application notes, reference designs and TI's Power Management Selection Guide are available through power.ti.com.
