Point-of-load Power Modules

( 1 Jul 2006 )

TI’s family of non-isolated, plug-in power modules provides fast transient response rates and reduces customers’ need for output capacitors. Featuring a tight 1.5% output voltage regulation, the point-of-load modules offer increased performance in a smaller footprint for designers of 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/DC conversion from a 4.5 to 14V input with adjustable output voltages down to 0.7V at output currents up to 50 A making them appropriate for intermediate bus architecture (IBA) applications. The T2 power modules feature 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% less output voltage deviation and a five to eight times reduction in output capacitance. Texas Instruments Inc.
