MIC2800-G1JSYML-TR

Overview

The MIC2800-G1JSYML-TR 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 linear regulators to provide three independent output rails. 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 1.15V/300mA LDO, and a 3.3V/300mA LDO. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-efficiency synchronous buck converter alongside two precision LDOs for combined switching and linear regulation capabilities.
• Features LowQ Mode technology designed to minimize quiescent current during light-load or standby conditions to enhance system efficiency.
• Includes a Power-On Reset (POR) circuit to ensure reliable system initialization by monitoring supply voltages.
• Utilizes digital control architecture allowing for flexible configuration and optimized performance across varying load profiles.

Applications

• Portable consumer electronics requiring efficient multi-rail power distribution
• Embedded systems needing simultaneous switching and linear regulation sources
• Battery-powered devices utilizing LowQ Mode for extended operational life

Procurement Notes

Verify the complete part number including suffixes to ensure correct output voltage configurations and packaging options. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Cross-reference official datasheets for specific thermal and electrical characteristics relevant to your design constraints.

Selection Notes

Select this component when a single IC solution is required to generate multiple voltage rails efficiently. The combination of a buck regulator and dual LDOs reduces component count compared to discrete solutions. Ensure the input voltage range aligns with the system's power source and that the output currents meet the load demands of the target application circuits.

Part Context

This part belongs to the MIC2800 series of specialized PMICs from Microchip Technology. The series focuses on providing integrated power management solutions for portable applications. Variants within the series differ primarily in fixed output voltages and specific feature sets while maintaining the same core topology and package footprint.

Replacement Considerations

Direct substitutes may include other MIC2800 variants with different fixed output voltages, such as MIC2800-G4MYML-TR or MIC2800-G8SYML-TR. Verify pin compatibility and output specifications before substitution. No alternative manufacturer equivalents are confirmed in the provided documentation.
