Texas Instruments TPS75003RHLR
The TPS75003 is a complete power management solution for FPGA, DSP and other multi-supplyapplications. 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 minimumvoltage-rail rise time. Independent enables for each output allow sequencing to minimize demand onthe power supply at start-up. Soft-start on each supply limits inrush current during start-up. Twointegrated buck controllers allow efficient, cost-effective voltage conversion for both low andhigh current supplies such as core and I/O. A 300-mA LDO is integrated to provide an auxiliary railsuch as VCCAUX on the Xilinx Spartan-3 FPGA. All three output voltages areexternally configurable for maximum flexibility.
The TPS75003 is fully specified from –40°C to +85°C and is offered in a VQFN package,yielding a highly compact total solution size with high power dissipation capability.
