MIC2800-G4SYML

Overview

The MIC2800-G4SYML is a digital power management integrated circuit manufactured by Microchip Technology, formerly Micrel. It integrates one buck converter and two low-dropout (LDO) linear regulators within a single 16-pin QFN package. The device operates with an input voltage range of 2.7 V to 5.5 V. The LDO outputs provide adjustable voltages ranging from 1.2 V to 3.3 V, supporting output currents up to 300 mA. The unit functions reliably across an industrial temperature range of -40°C to +125°C.

Feature Summary

• Integrates a switching regulator and dual linear regulators for combined power conversion and regulation
• Features LowQ Mode technology to optimize efficiency during light-load conditions
• Includes Power-On Reset (POR) functionality to ensure system stability during startup
• Utilizes digital control architecture for precise voltage regulation and monitoring

Applications

• Portable electronic devices requiring efficient multi-rail power distribution
• Industrial control systems operating in harsh thermal environments
• Embedded computing platforms needing stable logic and peripheral supply rails
• Communication equipment utilizing regulated voltage domains for signal integrity

Procurement Notes

Verify the manufacturer designation as Microchip Technology, noting the historical association with Micrel Inc. Confirm the specific suffix G4SYML corresponds to the required pinout and packaging configuration. Ensure compatibility with the intended input voltage range and load requirements before integration into the design.

Selection Notes

Select this component when a compact solution combining switching efficiency and linear regulation precision is required. The integrated POR feature simplifies system reset logic. Verify that the 16-pin QFN footprint fits the available PCB space and that the thermal performance meets the application's heat dissipation needs under maximum load conditions.

Part Context

This part belongs to the MIC2800 series of digital power management ICs. The series is designed to replace discrete power solutions, reducing board space and component count. The G4 suffix typically indicates lead-free compliance and specific manufacturing lot characteristics defined by the supplier.

Replacement Considerations

Consult official Microchip documentation for verified cross-reference part numbers. Substitutions must match the 16-pin QFN package and electrical specifications exactly. Generic equivalents are not recommended without rigorous validation against the original datasheet parameters.
