TPS75003RHLRG4

Power Management - Specialized Overview

The TPS75003RHLRG4 is a triple-supply power management IC designed for powering FPGAs and DSPs. It integrates two high-current buck converters capable of delivering up to 3 A each, and one low-dropout (LDO) regulator providing 300 mA. The device operates from an input voltage range of 2.2 V to 6.5 V. Output voltages are adjustable, with buck outputs ranging from 1.2 V to 6.5 V and the LDO output adjustable from 1.0 V to 6.5 V. It features a quiescent supply current of 75 µA and operates within a temperature range of -40°C to +85°C.

Power Management - Specialized Feature Summary

• Integrates three independent regulators: two 3 A buck converters and one 300 mA LDO.
• Configurable multi-rail architecture suitable for complex FPGA and DSP power sequencing.
• Optimized for efficiency with tested performance for Spartan-3 series FPGAs.

Power Management - Specialized Applications

• Powering Xilinx Spartan-3, Spartan-3E, and Spartan-3L FPGAs
• General-purpose FPGA core and I/O power supplies
• DSP system power management

Power Management - Specialized Procurement Notes

Verify the suffix 'G4' indicates lead-free composition and RoHS compliance as per Texas Instruments standards. Confirm the package type is 20-VQFN with exposed thermal pad. Ensure the ordering part number matches the specific reel or cut tape quantity requirements for your assembly line. Cross-reference the datasheet revision to ensure compatibility with your design specifications.

Power Management - Specialized Selection Notes

Select this component when a single IC solution is required to generate multiple voltage rails for programmable logic devices. It is appropriate for designs needing high current density from buck converters alongside a clean analog supply from the LDO. Consider the 20-pin QFN package constraints for thermal management and PCB layout space compared to discrete solutions.

Power Management - Specialized Part Context

This part belongs to the TPS75003 family of configurable multi-rail PMICs. It is specifically engineered to simplify the power design for Xilinx Spartan-3 family FPGAs by replacing multiple discrete components. The RHLRG4 designation specifies the 20-VQFN package, green material composition, and tape-and-reel packaging format.

Power Management - Specialized Replacement Considerations

The TPS75003RHLT is a pin-compatible alternative in the same series. Verify if the specific reel packaging or minor parameter tolerances differ between the RHLR and RHLT suffixes before substitution.
