TI Introduces 14 A Excalibur™ Plug-In Power Modules for Point-of-Load Applications

The manufacturer says... Chipcenter's
Nasser Kutkut, Ph.D., says...

Texas Instruments announced a new series of 14 A output, 5 V input plug-in power modules in 12-pin, 8 mm tall Excalibur™ packages targeted at point-of load applications such as high-end microprocessors and digital signal processors (DSPs). (See power.ti.com/sc03069).
TI's PT6460 modules, which are 50 percent smaller than previous generations of 14 A modules, operate from a 5 V input bus, and include output voltage options as low as 1.0 V of direct current. Other key features include:

94% efficiency;
pre-bias startup capability;
adjustable output voltage;
output remote sense;
on/off inhibit;
over-current protection;
surface-mount compatible;
IPC Lead-Free 2.

TI's PT6460 modules are packaged in a 12-pin low-profile Excalibur copper case that requires no heat sink and offers the advantages of solderability. Measuring 43 mm × 17 mm, the Excalibur cases meet critical 8 mm height tolerances in horizontal mounting, and are available in through-hole and surface-mount pin configurations.
PT6460 power modules are now available in volume from TI and its authorized distributors. Pricing per module in quantities of 1000 is $17.53.

A new series of point-of-load (POL) DC/DC converters from TI promises to offer significant size reduction while maintaining high conversion efficiencies and an adjustable output-voltage capability. POL converters offer on-demand distributed-power solutions, are less susceptible to line and distribution impedances, and have faster transient load response.
TI's new PT6460 converters are housed in a low-profile Excalibur package that requires no heat sinking, and are surface-mount compatible. The new POL converters are ideal for microprocessor and DSP point-of-load applications.
