TPS65086401RSKT

Special Purpose Regulators Overview

The TPS65086401RSKT is a configurable multirail power management unit (PMU) from Texas Instruments, designed for Xilinx Zynq UltraScale+ MPSoCs and FPGAs. It integrates multiple DC-DC converters and low-dropout regulators within a 64-pin VQFN package. The device supports an input voltage range of 3 V to 21 V and provides output voltages ranging from 410 mV to 5.1 V. Key current capabilities include outputs rated at 40 mA, 100 mA, 200 mA, 600 mA, and 3 A. It operates reliably across a temperature range of -40°C to +85°C.

Special Purpose Regulators Feature Summary

• Configurable multirail architecture tailored for complex system-on-chip power requirements
• Integrated high-current switching regulators supporting heavy processor loads
• Comprehensive protection mechanisms including thermal shutdown and overcurrent limiting

Special Purpose Regulators Applications

• Powering Xilinx Zynq UltraScale+ MPSoC devices
• Supplying power to FPGA logic and I/O banks
• Multicore processor system power distribution

Special Purpose Regulators Procurement Notes

Verify the specific suffix '01' against official Texas Instruments documentation to confirm exact pinout and configuration options. Ensure compatibility with the target Xilinx device's power sequencing requirements. Confirm moisture sensitivity level handling during assembly. Validate that the VQFN-64 footprint matches the design layout. Check for any recent product change notices affecting electrical characteristics or packaging.

Special Purpose Regulators Selection Notes

Select this component when designing systems based on Xilinx Zynq UltraScale+ architectures requiring a single PMIC solution. It is suitable for applications needing flexible voltage rails for core, memory, and peripherals. Consider the 64-VQFN package size constraints. Evaluate if the integrated regulator count meets all system rail requirements without external components. Verify input voltage availability aligns with the 3 V to 21 V operating range.

Special Purpose Regulators Part Context

This part belongs to the TPS650864 series, a family of PMUs optimized for Xilinx programmable logic devices. It shares architectural similarities with other TPS65086x variants but is specifically configured for the power domain requirements of UltraScale+ technology nodes. The series emphasizes configurability to adapt to different FPGA configurations and performance states.

Special Purpose Regulators Replacement Considerations

Consult the TPS650864 datasheet for direct pin-to-pin compatible alternatives within the same series. Verify that substitute parts maintain identical output current ratings and voltage ranges. Ensure replacement components support the same Zynq UltraScale+ power sequencing protocols.
