MCP16701T-I/KCX

Power Management - Specialized Overview

The MCP16701T-I/KCX is a specialized Power Management IC (PMIC) from Microchip Technology, designed for high-end microcontroller, FPGA, and DSP power applications. It integrates eight buck converters and four low-dropout regulators (LDOs). The device operates within an input voltage range of 2.7 V to 5.5 V. Buck outputs support currents up to 1.5 A, while LDOs provide 300 mA. Output voltages are adjustable from 3.8 mV to 3.8 V. It is housed in a 64-pin VQFN package and functions reliably between -40°C and +85°C.

Power Management - Specialized Feature Summary

• Integrates eight independent buck converters and four LDOs for comprehensive multi-rail power management
• Includes integrated EEPROM for configuration storage and system monitoring
• Supports true output disconnect for boost topologies in related family members

Power Management - Specialized Applications

• Powering complex microcontrollers and MPUs
• Supplying power to Field-Programmable Gate Arrays (FPGAs)
• Digital Signal Processor (DSP) power systems

Power Management - Specialized Procurement Notes

Verify the complete part number including suffixes such as 'I' for temperature grade and 'K' for package type against official datasheets. Confirm RoHS compliance status and moisture sensitivity levels prior to ordering. Ensure the procurement channel provides valid traceability documentation. Cross-reference the specific revision level with design requirements to avoid compatibility issues during integration.

Power Management - Specialized Selection Notes

Select this component when a single IC solution is required to manage multiple voltage rails for high-performance processing units. The integration of eight buck converters reduces board space compared to discrete solutions. Verify that the required output currents and voltage ranges align with the device's specified capabilities. Consider the VQFN-64 package thermal performance for the target application environment.

Power Management - Specialized Part Context

This PMIC belongs to the MCP16701 series, which targets automotive and industrial high-end computing applications. It is distinct from simpler regulator families by offering extensive channel counts. The device supports PCI100x automotive switch power solutions. It serves as a central power management unit for systems requiring precise voltage regulation across numerous digital logic domains.

Power Management - Specialized Replacement Considerations

Check for direct pin-compatible alternatives within the same Microchip PMIC portfolio. Verify if other models offer similar channel counts or specific voltage configurations. Ensure any substitute maintains compatibility with the existing EEPROM interface and control logic.
