MIC2810-44MYML-TR

Overview

The MIC2810-44MYML-TR is a power management IC from Microchip Technology, integrating one DC-DC buck converter and two linear regulators. It operates with an input voltage range of 2.7 V to 5.5 V. The switching regulator provides up to 600 mA output current with adjustable voltage from 0.8 V to 3.6 V. The two LDOs deliver fixed outputs of 1.2 V each at 300 mA, while the third output is fixed at 2.8 V with 600 mA capability. The device features LowQ mode for reduced quiescent current and includes Power-On Reset (POR) functionality. It is housed in a 16-pin MLF package.

Feature Summary

• Integrates a synchronous buck converter with two low-dropout linear regulators on a single chip.
• Includes LowQ mode operation to minimize quiescent current consumption during light load conditions.
• Features integrated Power-On Reset (POR) circuitry to ensure system stability upon power-up.
• Supports wide input voltage ranges suitable for battery-powered portable applications.

Applications

• Portable consumer electronics requiring multi-rail power supplies
• Battery-operated devices needing efficient step-down conversion
• Systems utilizing Power-On Reset for reliable initialization

Procurement Notes

Verify the specific suffix '44MYML' against official Microchip documentation to confirm fixed output voltages and package type. Ensure compatibility with RoHS standards if required by your manufacturing process. Confirm that the 16-MLF package dimensions match your PCB footprint design. Check moisture sensitivity levels for proper storage and reflow soldering profiles.

Selection Notes

Select this component when a combined solution for switching regulation and linear filtering is needed. The fixed 1.2 V and 2.8 V outputs simplify design for standard logic levels. Consider the 600 mA capacity of the buck converter for main rail requirements. Verify thermal performance within the MLF package for your specific ambient temperature constraints.

Part Context

This part belongs to the MIC2810 family of mixed-signal power management ICs. These devices are designed to replace multiple discrete components, reducing board space and assembly complexity. The family typically targets portable applications where efficiency and size are critical constraints.

Replacement Considerations

Check Microchip's official cross-reference lists for direct pin-compatible alternatives. Verify that any substitute maintains the same output voltage configuration and current ratings. Ensure the replacement supports the same MLF package or requires adapter solutions.
