Modules put low voltages
at the point of load
Texas Instruments has released six new POLA nonisolated plug-in power modules for telecomms and datacommunications applications that require a low output voltage rail
The new easy-to-use, 12V modules can deliver up to 26A of output current, and support adjustable output voltages from 0.8 to 1.8V with up to 90% power efficiency. The low-voltage PTH modules feature TI's Auto-Track sequencing technology, which simplifies power up and power down of multiple modules.

TI will showcase the latest mobile products that enable its customers to innovate in a world driven by demand for on-the-go entertainment and productivity at CTIA Wireless 2006
Auto-Track makes it easy for power supply designers to meet I/O and core voltage sequencing requirements in high performance processors, applications specific integrated circuits (ASICs) and digital signal processing (DSP) engines.
All six devices include a load fault protection feature by including a nonlatching overcurrent trip.
In addition, a prebias startup function prevents the modules from sinking current in applications where an external voltage is present at the module's output during startup, such as voltage that is fed back through an FPGA or ASIC.
To ensure tighter load regulation at higher currents, the 10, 12, 18 and 26A modules include an output voltage remote sense feature.
As POLA products, each PTH module is ensured a pin-compatible footprint with the same electrical designs for assured interoperability, giving designers a true second source option for their design.
The new low-voltage PTH modules highlighted in the chart below are available in volume today from TI and the company's authorised distributors.
The compact devices come in a double-sided, surface mount construction and are available in horizontal through-hole or surface-mount styles.
Suggested pricing per 1,000 units $9.95 for the 6A modules; $11.50 for the 10A modules; $13.95 for the 12A; $18.15 for the 18A; and $24.60 for the 26A modules.
