Integrated Triple Supply Power Management IC For Xilinx(R) Spartan(TM)-3 FPGAs

The TPS75003 is a complete Power Management solution for FPGA DSP and other multi-supply applications. The device has been tested with and meets all of the Xilinx Spartan-3, Spartan-3E and Spartan-3L start-up profile requirements, including monotonic voltage ramp and minimum voltage rail rise time. Independent Enables for each output allow sequencing to minimize demand on the power supply at start-up. Soft-start on each supply limits inrush current during start-up. Two integrated buck controllers allow efficient, cost-effective voltage conversion for both low and high current supplies such as core and I/O. A 300mA LDO is integrated to provide an auxiliary rail such as VCCAUX on the Xilinx Spartan-3 FPGA All three supply voltages are offered in user-programmable options for maximum flexibility.
The TPS75003 is fully specified from ?40C to +85C and is offered in a QFN package, yielding a highly compact total solution size with high power dissipation capability.
