Texas Instruments Inc. (TI, Dallas, TX) announced its new 50 A PTH12040 and 60 A PTH04040 plug-in power modules that extend TI's PTHxx family of non-isolated modules. The POLA™-compatible, non-isolated, plug-in power modules offer a multi-phase switching topology. achieve a power conversion efficiency up to 96%, and are capable of powering densely populated power systems found in advanced computing platforms and servers.
The PTH12040 and PTH04040 power modules combine a wide range of input voltages and feature Auto-Track™ sequencing, which allows the outputs of multiple modules to track one another or a common voltage during power-up and power-down transitions. In addition to the Auto-Track technology, both modules incorporate an on/off inhibit, margin up/down controls, differential remote output-voltage sense, output over-current and over-temperature shutdown, and a programmable under-voltage lockout function that allows the turn-on threshold to be customized.
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 suitable 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 powers advanced computing systems that use either a 3.3 V or 5 V distribution bus.
The PTH12040 and PTH04040 modules are now available in through-hole and low-profile, double-sided, surface-mount packages. Pricing for the PTH12040 is $35 for 1,000-unit quantities, and $35 for the PTH04040 in 1,000-unit quanities.
