MP5470GL-0000-P

Overview

The MP5470GL-0000-P is a power management IC from Monolithic Power Systems featuring four integrated high-efficiency step-down DC/DC converters. It supports an input voltage range of 4V to 16V and provides output currents of 3A, 3A, 2A, and 2A respectively. The device includes I2C and MTP interfaces for configuration. It operates within a temperature range of -40°C to +85°C and utilizes a QFN-22 package.

Feature Summary

• Integrates four independent synchronous buck converters for multi-rail power distribution
• Supports flexible logic control via I2C and MTP interfaces
• Includes overvoltage protection mechanisms for system reliability

Applications

• General purpose power management in embedded systems
• Overvoltage protection circuits
• Multi-voltage rail generation for digital logic and peripherals

Procurement Notes

Verify the specific suffix (P vs Z) against the manufacturer's current datasheet to confirm pinout compatibility and internal configuration differences. Ensure the ordering code matches the required package variant and temperature grade. Cross-reference with official MPS documentation to validate availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a single IC solution is required to generate multiple regulated voltages from a 4V to 16V input source. It is suitable for designs needing integrated overvoltage protection and programmable logic control. Consider the QFN-22 package constraints and thermal requirements for the specified current loads of up to 3A per channel.

Part Context

This part belongs to the MP5470 family of complete power management ICs designed by Monolithic Power Systems. The series integrates multiple step-down converters and logic interfaces into a compact form factor, targeting applications that require efficient multi-output power regulation without external discrete components.

Replacement Considerations

Check for MP5470GL-0000-Z as a potential variant with different suffix specifications. Verify functional equivalence with other MPS PMICs offering four buck converters if supply chain constraints exist.
