Texas Instruments Inc. (TI, Dallas, TX) announced a highly efficient, power management integrated circuit (IC) for Xilinx's Spartan™-II/IIE/3 series of field programmable gate arrays (FPGAs). The new triple-channel device reduces the number of external components required to power a complete FPGA system used in consumer, communications and digital video applications.
The new TPS75003 device integrates two 3 A dc-dc buck controllers with up to 95% efficiency to power the Spartan core and I/O rails, and one 300 mA low dropout (LDO) regulator that is stable with a low-cost ceramic output capacitor for powering the Spartan-3's Vccaux rail or other low-power system voltage. Combining increased design flexibility with cost-effective voltage conversion, the device includes programmable soft-start for in-rush current control and independent enables for sequencing.
Samples of the new TPS75003 are currently available. Volume production is scheduled for the fourth quarter. Packaged in a low-profile, 4.5 mm x 3.5 mm x 0.9 mm, 20-pin QFN package, pricing is $1.90 per unit in quantities of 1,000.
