MIC2800-G4KYML

Overview

The MIC2800-G4KYML is a digital power management IC from Microchip Technology, housed in a 16-pin QFN package. It integrates one buck converter and two low-dropout (LDO) linear regulators. The device operates with an input voltage range of 2.7V to 5.5V and supports switching frequencies up to 2MHz. Output specifications include a 1.8V/600mA buck channel, a 1.2V/300mA LDO, and a 2.8V/300mA LDO. It functions within a temperature range of -40°C to 125°C.

Feature Summary

• Integrates a synchronous buck regulator with two independent LDOs for multi-rail power distribution.
• Features Low-Q Mode operation to optimize efficiency under light load conditions.
• Includes Power-On Reset (POR) circuitry to ensure system stability during startup.
• Utilizes digital control architecture for precise regulation and monitoring capabilities.

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Embedded systems needing integrated power management solutions
• Industrial equipment operating in wide temperature environments

Procurement Notes

Verify the specific suffix 'G4KYML' against official Microchip documentation to confirm exact output voltages and current ratings, as variations exist within the MIC2800 family. Ensure compatibility with RoHS3 standards and check moisture sensitivity level requirements for surface mount assembly processes.

Selection Notes

Select this component when a compact solution combining switching and linear regulation is required. Consider the 16-QFN footprint for space-constrained designs. Verify that the input voltage range of 2.7V to 5.5V aligns with the system supply. Evaluate thermal performance given the high current capability of the buck output.

Part Context

This part belongs to the MIC2800 series of digital power management ICs originally developed by Micrel, now manufactured by Microchip Technology. The series is designed for applications requiring efficient power conversion with minimal external components. The G4 suffix typically indicates lead-free and halogen-free compliance.
