Point of load

has launched a family of non-isolated, plug-in power modules with a new technology that provides fast transient response rates and reduces customers' need for output capacitors.

Featuring a 1.5 percent output voltage regulation, the point-of-load modules are targeted at designers of 3G wireless infrastructure, networking and communication systems that use DSPs, FPGAs, ASICs and microprocessors.

Extending TI's line of PTH devices, the T2 series of point-of-load modules will support step-down DC/DC conversion from a wide 4.5V to 14V input with adjustable output voltages down to 0.7V at output currents up to 50A making them suitable for intermediate bus architecture (IBA) applications.

The T2 power modules feature a new TurboTrans technology, which allows a power supply designer to dynamically "tune" the modules using a single external resistor to meet a specific transient load requirement. The end-result is faster transient response with 40 percent less output voltage deviation and a five to eight times reduction in output capacitance. In addition, system stability is enhanced when using ultra-low equivalent series resistance (ESR) polymer tantalum or ceramic capacitors.
