The TPS75003 is a complete power management solution for FPGAs, DSPs, and other multi-power applications. The device has been tested to meet the requirements of all Spartan-3E and Spartan-3L start-up profiles with the Xilinx Spartan-3, including monotonous ramp voltage and lowest voltage rail rise time. Allows each output to be allowed to be sequenced independently to reduce start-up on the demand for power supply. The inrush current per power supply for soft start is limited to start-up. Two integrated step-down controllers allow for high efficiency such as low core and high current supply, low-cost voltage conversion and I/O The 300mA LDO is available with an integrated-3 FPGA for an auxiliary rail Spartan such as V CCAUX in Xilinx. All three supply voltages provide maximum flexibility in user-programmable options.
