MP28310GC-P

Overview

The MP28310GC-P is a monolithic power management unit from Monolithic Power Systems, integrating a high-efficiency 300mA step-down converter and a 100mA low-dropout regulator. It operates with an input voltage range of 2V to 5.5V and features ultra-low quiescent current of 500nA. The device utilizes a 1.5MHz switching frequency and is housed in a compact 12-CSP (1.2x1.6mm) package.

Feature Summary

• Integrates a 300mA buck converter and a 100mA LDO in a single chip
• Ultra-low 500nA quiescent current for extended battery life
• Compact 12-CSP package for space-constrained designs

Applications

• Single-cell lithium-ion battery powered devices
• USB-powered portable electronics
• Multi-cell battery applications

Procurement Notes

Verify the specific suffix 'P' against official MPS documentation to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with the 12-CSP footprint and thermal constraints during integration.

Selection Notes

Select this component when designing systems requiring dual regulated outputs from a single source. The integrated LDO provides clean power for sensitive analog sections while the buck converter handles higher current loads efficiently.

Part Context

This part belongs to the MP series of power management ICs by Monolithic Power Systems. It is designed for portable applications where size and efficiency are critical. The GC-P designation indicates the specific package type and lead-free compliance status.

Replacement Considerations

MP28310GC-Z is a verified substitute with identical electrical specifications and pinout, differing only in packaging format.
