MIC2800-G4MYML-TR

Overview

The MIC2800-G4MYML-TR is a digital power management IC from Microchip Technology, housed in a 16-pin QFN package. It integrates one buck converter and two linear regulators within a single component. The device operates with an input voltage range of 2.7 V to 5.5 V. Output specifications include a 1.8 V regulator capable of 600 mA, alongside two additional regulators providing 1.2 V and 2.8 V at 300 mA each. The switching frequency is fixed at 2 MHz. It supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates a high-current buck converter with two low-dropout linear regulators for multi-rail power distribution.
• Features LowQ Mode technology designed to optimize efficiency during light-load or standby conditions.
• Includes a Power-On Reset (POR) circuit to ensure system stability during power-up sequences.
• Utilizes digital control architecture for precise regulation and monitoring capabilities.

Applications

• Portable electronic devices requiring efficient multi-voltage rail generation
• Embedded systems needing integrated power management solutions
• Industrial equipment operating in extended temperature environments

Procurement Notes

Verify the complete part number including suffixes to confirm specific output configurations and packaging options. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Ensure compatibility with existing PCB footprint designs for the 16-QFN package. Check for any recent product change notices regarding assembly sites or material updates.

Selection Notes

Select this component when a compact solution combining switching and linear regulation is required. The 600 mA buck output suits moderate load applications while the LDOs provide clean power for sensitive circuits. Consider the 2 MHz switching frequency for smaller external passive components. Verify that the input voltage range aligns with the system's power source availability.

Part Context

This part belongs to the MIC2800 series of digital power management ICs. The series offers various output configurations tailored for different application needs. The G4MYML suffix indicates specific factory coding and packaging details. It represents a consolidated approach to power design by reducing component count and board space.

Replacement Considerations

Check for other MIC2800 variants with different output voltages if the current configuration does not match requirements. Verify pin-to-pin compatibility before substituting with similar PMICs from other manufacturers.
