MP5423GN-P

Overview

The MP5423GN-P is a specialized multi-channel power management IC from Monolithic Power Systems, designed for high-voltage applications. It integrates a synchronous buck converter capable of delivering up to 300 mA output current alongside two low-dropout regulators (LDOs). The device operates within an input voltage range of 25 V to 100 V, making it suitable for systems requiring robust power regulation under varying line conditions. The maximum adjustable output voltage reaches 14 V, while the LDO outputs provide fixed or adjustable voltages between 3.3 V and 14 V. Packaged in an SOIC-8 surface-mount format, this PMIC consolidates multiple power rails into a single compact solution.

Feature Summary

• Integrates a high-voltage buck converter with dual LDOs for consolidated power rail generation
• Supports wide input voltage ranges up to 100 V for flexible system integration
• Designed specifically for electric bike power management architectures

Applications

• Electric-bike power management systems
• High-voltage battery-powered equipment
• Multi-rail industrial control units

Procurement Notes

Verify the specific suffix designation to confirm packaging configuration, as variants exist for reel and cut tape formats. Ensure compatibility with moisture sensitivity levels during storage and handling procedures. Cross-reference the exact part number against official manufacturer documentation to validate pinout assignments and thermal performance characteristics before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require a single IC solution for managing both high-current buck conversion and lower-power linear regulation from a high-voltage source. The integrated nature reduces board space compared to discrete solutions. Verify that the required output currents and voltage levels align with the specified 300 mA buck limit and LDO capabilities.

Part Context

This part belongs to the MP5423 series of professional power management ICs. It shares functional similarities with the MP5423GN-Z variant, differing primarily in packaging quantities and distribution channels. Both variants serve the same core application in electric mobility power systems, providing integrated regulation for complex electronic loads.

Replacement Considerations

The MP5423GN-Z serves as a direct functional alternative within the same series. Verify package compatibility and ordering unit requirements when substituting.
