The TPS75003 is a triple-supply power management IC from Texas Instruments (TI) that integrates two 95% efficient 3A buck controllers and one 300mA LDO to provide a complete power management solution for FPGAs, DSPs, 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 fixed voltage output configurations to enhance design flexibility.
