TI Introduces POLA™ Compatible SIP Power Modules

May 13, 2004

DALLAS (May 13, 2005) -- Texas Instruments Incorporated (TI) today announced two families of POLATM compatible, non-isolated, plug-in power modules that are available in single in-line pin (SIP) packages. The flexible 8-A and 18-A point-of-load power modules support input voltages of 3.3-V, 5-V and 12-V. Additionally, the modules simplify power design in multi-voltage systems employing high-speed microprocessors, FPGAs, ASICs and TI´s TMS320TM digital signal processors (DSPs) in an intermediate bus power architecture.

The PTVxx010 family of DC/DC converters combines high-performance and high power efficiency with double-sided, surface-mount construction. The 8-pin SIP footprint minimizes board space and offers an alternative package option for space-conscious applications, such as high-end computers and servers. The PTVxx010 provides step-down conversion to a wide range of output voltages, at up to 8-A of output current. The output voltage can be set any value between 0.8-V to 1.8-V, 2.5-V or 3.6-V, depending upon the device's input voltage.
In addition to the PTVxx010 series for 8-A, TI also introduced its PTVxx020 family of 12-pin SIP modules that support similar systems requiring output currents of up to 18-A. Both families include Auto-TrackTM sequencing technology to simplify the task of supply-voltage sequencing in a power system by enabling the output voltage of multiple modules to accurately track each other, or any external voltage, during power up and power down. 

POLA Compatibility

TI´s PTH and PTV families of non-isolated plug-in modules are fully POLA-compatible. Members of the POLA Alliance offer customers advanced, non-isolated modules with the same footprint and form factor. POLA parts are also ensured to be interoperable, providing customers with true second-source availability.


Availability, Packaging and Pricing

The PTVxx010 and PTVxx020 integrated power modules are available in volume today from TI and the company´s authorized distributors. Suggested pricing for the PTVxx010 products is $6.90 per 1,000 units, and $11.60 for the PTVxx020 per 1,000 units. Evaluation modules, application notes, reference designs and TI´s Power Management Selection Guide are available through power.ti.com.
