The TPS75003 power management IC for Xilinx® Spartan™-II,
Spartan-IIE, and Spartan-3 FPGAs integrates multiple functions
to significantly reduce the number of external components
required – and simply your designs. Combining increased
design flexibility with cost-effective voltage conversion, the
device includes programmable softstart for in-rush current control
and independent enables for sequencing the three channels.
The TPS75003 meets all Xilinx startup profile requirements,
including monotonic ramp and minimum ramp times.
