TI Introduces 2.25-A and 3-A POLA™ Power Modules with Auto-Track™ Sequencing

Jul 6, 2005

DALLAS (July 6, 2005) -- Texas Instruments Incorporated (TI) today announced its first 2.25-A and 3-A non-isolated, plug-in power modules with TI's Auto-TrackTM sequencing technology. The POLATM-compatible modules simplify power design in industrial and data communications systems that employ high-speed microprocessors, FPGAs, ASICs and TI's TMS320TM digital signal processors (DSPs). See: www.ti.com/sc05143.

The new 2.25-A PTH08000W and 3-A PTH04000W plug-in power modules support an adjustable output voltage range down to 0.9-V at a power conversion efficiency up to 94 percent. The flexible converters' unique Auto-Track sequencing feature allows the outputs of multiple modules to track one another or a common voltage during power-up and power-down transitions.
The PTH08000W operates at input voltages from 4.5-V to 14-V, and can supply an output current of up to 2.25-A with output voltages of 5.5-V to 0.9-V, making it ideal for systems that use a 12-V intermediate distribution bus. The 3-A PTH04000W module supports input voltages from 3-V to 5.5-V, and can support output voltages from 0.9-V to 3.6-V. The 3-A module efficiently meets all power requirements for industrial, medical, and test and measurement systems that require a 3.3-V or 5-V distribution bus.
Both modules include several power protection features, including an on/off inhibit and thermal shutdown, overcurrent protection and under-voltage lockout.


The PTH08000W and PTH04000W power 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 PTH08000W and PTH04000W are $4.50 per 1,000 units.
