Overview
The TPS75003RHLR is a highly integrated and configurable Power Management IC (PMIC) designed by Texas Instruments. This device is tailored for power management in complex systems such as Field-Programmable Gate Arrays (FPGAs), Digital Signal Processors (DSPs), and other multi-supply applications. It has been tested and endorsed by Xilinx for powering the Spartan™-3, Spartan-3E, and Spartan-3L FPGAs, ensuring it meets all the start-up profile requirements including monotonic voltage ramp and minimum voltage-rail rise time.
The TPS75003RHLR features two high-efficiency buck controllers and one low-dropout linear regulator (LDO), providing flexible and efficient voltage conversion. The device is packaged in a small, low-profile 4.5mm × 3.5mm × 0.9mm VQFN package, making it ideal for space-constrained designs while offering high power dissipation capability.
