(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings nly, and functional operation of the device at these or any other conditions beyond those indicated under the Electrical Characteristics s not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.

The TPS75003_1136181 is a complete power management solution for FPGA, DSP and other multi-supply appli-cations. The device has been tested with and meets all of the Xilinx Spartan-3 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 oneach supply of TPS75003_1136181 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 V_CCAUX on the Xilinx Spartan-3 FPGA. All three supply voltages of TPS75003_1136181 are offered in user-programmable options for maximum flexibility.

The TPS75003_1136181 is fully specified from -40 to +85 and is offered in a QFN package, yielding a highly compact total solution size with high power dissipation capability.
