Texas Instruments Inc. (TI) announced two families of POLA compatible, non-isolated, plug-in power modules that are available in single in-line pin (SIP) packages. The flexible 8A and 18A point-of-load power modules support input voltages of 3.3V, 5V and 12V. Additionally, these new modules simplify power design in multi-voltage systems employing high-speed microprocessors, FPGAs, ASICs and TI's tms320 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 8A of output current. The output voltage can be set any value between 0.8V to 1.8V, 2.5V or 3.6V, depending upon the device's input voltage.

In addition to the PTVxx010 series for 8A, 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-Track 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.

Both the PTH and PTV families of non-isolated plug-in modules are fully POLA-compatible. Ti explained that 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.

The PTVxx010 and PTVxx020 integrated power modules are available in volume orders, with a suggested pricing of $6.90 for the PTVxx010 products, and $11.60 for the PTVxx020.
