Texas Instruments announced a family of non-isolated, plug-in power modules that provide ultra-fast transient response rates. In addition, the devices reduce the need for output capacitors. Featuring a 1.5% output voltage regulation, the point-of-load modules are suited for such applications as 3G wireless infrastructure, networking, and communication systems that use advanced DSPs, FPGAs, ASICs, and microprocessors.
The T2 series of point-of-load modules will support step-down dc-to-dc conversion from a 4.5- to 14-V input with adjustable output voltages down to 0.7 V at output currents up to 50 A. The power modules are built with TI's TurboTrans technology, which allows a power supply designer to dynamically tune the modules using one external resistor to meet a specific transient load requirement. The end-result is faster transient response with less output voltage deviation and a reduction in output capacitance. In addition, system stability is enhanced when using ultra-low equivalent series resistance (ESR) polymer tantalum or ceramic capacitors.
The T2 power modules are now available in sample quantities. Pricing per module in quantities of 1000 begins at $7.90. More information is available at www.ti.com/sc05226.
